Is there a built-in way to measure execution time of a command on the Windows command line?

PowerShell has a cmdlet for this called Measure-Command. You’ll have to ensure that PowerShell is available on the machine that runs it.

PS> Measure-Command { echo hi }

Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 0
Milliseconds      : 0
Ticks             : 1318
TotalDays         : 1.52546296296296E-09
TotalHours        : 3.66111111111111E-08
TotalMinutes      : 2.19666666666667E-06
TotalSeconds      : 0.0001318
TotalMilliseconds : 0.1318

Measure-Command captures the command’s output. You can redirect the output back to your console using Out-Default:

PS> Measure-Command { echo hi | Out-Default }
hi

Days              : 0
...

Measure-Command returns a TimeSpan object, so the measured time is printed as a bunch of fields. You can format the object into a timestamp string using ToString():

PS> (Measure-Command { echo hi | Out-Default }).ToString()
hi
00:00:00.0001318

If the command inside Measure-Command changes your console text color, use [Console]::ResetColor() to reset it back to normal.

If you want

1. To measure execution time down to the hundredth of a second in (hh:mm:ss.ff format)
2. To not have to download and install a resource pack
3. To look like a huge DOS nerd (who doesn’t)

Try copying the following script into a new batch file (e.g. timecmd.bat):

@echo off
@setlocal

set start=%time%

:: Runs your command
cmd /c %*

set end=%time%
set options="tokens=1-4 delims=:.,"
for /f %options% %%a in ("%start%") do set start_h=%%a&set /a start_m=100%%b %% 100&set /a start_s=100%%c %% 100&set /a start_ms=100%%d %% 100
for /f %options% %%a in ("%end%") do set end_h=%%a&set /a end_m=100%%b %% 100&set /a end_s=100%%c %% 100&set /a end_ms=100%%d %% 100

set /a hours=%end_h%-%start_h%
set /a mins=%end_m%-%start_m%
set /a secs=%end_s%-%start_s%
set /a ms=%end_ms%-%start_ms%
if %ms% lss 0 set /a secs = %secs% - 1 & set /a ms = 100%ms%
if %secs% lss 0 set /a mins = %mins% - 1 & set /a secs = 60%secs%
if %mins% lss 0 set /a hours = %hours% - 1 & set /a mins = 60%mins%
if %hours% lss 0 set /a hours = 24%hours%
if 1%ms% lss 100 set ms=0%ms%

:: Mission accomplished
set /a totalsecs = %hours%*3600 + %mins%*60 + %secs%
echo command took %hours%:%mins%:%secs%.%ms% (%totalsecs%.%ms%s total)

Usage

If you put timecmd.bat in a directory in your path, you can call it from anywhere like this:

timecmd [your command]

E.g.

C:\>timecmd pause
Press any key to continue . . .
command took 0:0:1.18

If you want to do output redirection, you can quote the command like this:

timecmd "dir c:\windows /s > nul"

This should handle commands that run from before- to after-midnight, but the output will be wrong if your command runs for 24 hours or more.

Hehe, the most simple solution might be this:

echo %time%
YourApp.exe
echo %time%

This works on every Windows out of the box.

In case of an application using console output, it might be convenient to store the starting time in a temporary variable:

set startTime=%time%
YourApp.exe
echo Start Time: %startTime%
echo Finish Time: %time%

Just a little expansion of the answer from Casey.K about using the Measure-Command from PowerShell:

1. You can invoke PowerShell from the standard command prompt, like this:

   powershell -Command "Measure-Command {echo hi}"
   

2. This will eat the standard output, but you can prevent that by adding | Out-Default like this from PowerShell:

   Measure-Command {echo hi | Out-Default}
   

   Or from a command prompt:

   powershell -Command "Measure-Command {echo hi | Out-Default}"
   

Of course, you’re free to wrap this in a script file *.ps1 or *.bat.

The one-liner I use in Windows Server 2008 R2 is:

cmd /v:on /c "echo !TIME! & *mycommand* & echo !TIME!"

So long as mycommand doesn’t require quotes (which screws with cmd’s quote processing). The /v:on is to allow for the two different TIME values to be evaluated independently rather than once at the execution of the command.

If you have a command window open and call the commands manually, you can display a timestamp on each prompt, e.g.

prompt $d $t $_$P$G

It gives you something like:

23.03.2009 15:45:50,77

C:\>

If you have a small batch script that executes your commands, have an empty line before each command, e.g.

(empty line)

myCommand.exe

(next empty line)

myCommand2.exe

You can calculate the execution time for each command by the time information in the prompt. The best would probably be to pipe the output to a textfile for further analysis:

MyBatchFile.bat > output.txt

Since others are recommending installing things like freeware and PowerShell, you could also install Cygwin, which would give you access to many basic Unix commands like time:

abe@abe-PC:~$ time sleep 5

real    0m5.012s
user    0m0.000s
sys 0m0.000s

Not sure how much overhead Cygwin adds.

Not quite as elegant as some of the functionality on Unix, but create a cmd file which looks like:

@echo off
time < nul
yourexecutable.exe > c:\temp\output.txt
time < nul
rem on newer windows system you can try time /T

That will display the start and stop times like so:

The current time is: 10:31:57.92
Enter the new time:
The current time is: 10:32:05.94
Enter the new time:

I use freeware called «GS Timer».

Just make a batch file like this:

timer
yourapp.exe
timer /s

If you need a set of times, just pipe the output of timer /s into a .txt file.

You can get it here: Gammadyne’s Free DOS Utilities

The resolution is 0.1 seconds.

I’m using Windows XP and for some reason timeit.exe does not work for me. I found another alternative — PTIME. This works very well.

http://www.pc-tools.net/win32/ptime/

Example —

C:\> ptime

ptime 1.0 for Win32, Freeware - http://www.pc-tools.net/
Copyright(C) 2002, Jem Berkes <[email protected]>

Syntax: ptime command [arguments ...]

ptime will run the specified command and measure the execution time
(run time) in seconds, accurate to 5 millisecond or better. It is an
automatic process timer, or program timer.


C:\> ptime cd

Execution time: 0.015 s

There’s also TimeMem (March 2012):

This is a Windows utility which executes a program and displays its
execution time, memory usage, and IO statistics. It is similar in
functionality to the Unix time utility.

As long as it doesn’t last longer than 24hours…

@echo off

set starttime=%TIME%
set startcsec=%STARTTIME:~9,2%
set startsecs=%STARTTIME:~6,2%
set startmins=%STARTTIME:~3,2%
set starthour=%STARTTIME:~0,2%
set /a starttime=(%starthour%*60*60*100)+(%startmins%*60*100)+(%startsecs%*100)+(%startcsec%)

set /a endtime=(%endhour%*60*60*100)+(%endmins%*60*100)+(%endsecs%*100)+(%endcsec%)

set /a timetaken= ( %endtime% - %starttime% )
set /a timetakens= %timetaken% / 100
set timetaken=%timetakens%.%timetaken:~-2%

echo.
echo Took: %timetaken% sec.

Here is a

Postfix timer version:

Usage example:

timeout 1 | TimeIt.cmd

Execution took  ~969 milliseconds.

Copy & paste this into some editor like for example Notepad++ and save it as TimeIt.cmd:

:: --- TimeIt.cmd ----

    setlocal enabledelayedexpansion

    call :ShowHelp

    :: Set pipeline initialization time

    :: Set time at which stdin was ready
    set t2=!time!


    :: Calculate difference
    Call :GetMSeconds Tms1 t1
    Call :GetMSeconds Tms2 t2

    set /a deltaMSecs=%Tms2%-%Tms1%
    echo Execution took ~ %deltaMSecs% milliseconds.

    endlocal

Depending on the version of Windows you’re using, just running bash will put you into Bash mode. This will allow you to use a bunch of commands that are not available on PowerShell directly (like the time command). Timing your command is now as easy as executing:

# The clause <your-command> (without the angle brackets) denotes the command you want to run.
$ time <your-command>

Note: You can easily quit from Bash mode and return back into your mainstream shell by running exit while in Bash mode.

This worked for me perfectly (Windows 10) after trying out other methods (like Measure-Command) which sometimes produce undesired stats. Hope this works for you as well.

An alternative to measure-time is simply «Get-Date». You don’t have that hassle with forwarding output and so on.

$start = Get-Date
[System.Threading.Thread]::Sleep(1500)
$(Get-Date) - $start

Output:

Days              : 0
Hours             : 0
Minutes           : 0
Seconds           : 1
Milliseconds      : 506
Ticks             : 15060003
TotalDays         : 1.74305590277778E-05
TotalHours        : 0.000418333416666667
TotalMinutes      : 0.025100005
TotalSeconds      : 1.5060003
TotalMilliseconds : 1506.0003

This is a one-liner which avoids delayed expansion, which could disturb certain commands:

cmd /E /C "prompt $T$$ & echo.%TIME%$ & COMMAND_TO_MEASURE & for %Z in (.) do rem/ "

The output is something like:

14:30:27.58$
...
14:32:43.17$ rem/ 

For long-term tests replace $T by $D, $T and %TIME% by %DATE%, %TIME% to include the date.

To use this inside of a batch file, replace %Z by %%Z.

Update

Here is an improved one-liner (without delayed expansion too):

cmd /E /C "prompt $D, $T$$ & (for %# in (.) do rem/ ) & COMMAND_TO_MEASURE & for %# in (.) do prompt"

The output looks similar to this:

2015/09/01, 14:30:27.58$ rem/ 
...
2015/09/01, 14:32:43.17$ prompt

This approach does not include the process of instancing a new cmd in the result, nor does it include the prompt command(s).

Here is my method, no conversion and no ms. It is useful to determine encoding durations (limited to 24 hours though):

@echo off

:start
REM Start time storage
set ST=%time%
echo Process started at %ST%
echo.
echo.

REM Your commands
REM Your commands
REM Your commands

:end
REM Start Time Definition
for /f "tokens=1-3 delims=:" %%a in ("%ST%") do set /a h1=%%a & set /a m1=%%b & set /a s1=%%c

REM End Time Definition
for /f "tokens=1-3 delims=:" %%a in ("%TIME%") do set /a h2=%%a & set /a m2=%%b & set /a s2=%%c

REM Difference
set /a h3=%h2%-%h1% & set /a m3=%m2%-%m1% & set /a s3=%s2%-%s1%

REM Time Adjustment
if %h3% LSS 0 set /a h3=%h3%+24
if %m3% LSS 0 set /a m3=%m3%+60 & set /a h3=%h3%-1
if %s3% LSS 0 set /a s3=%s3%+60 & set /a m3=%m3%-1

echo Start    :    %ST%
echo End    :    %time%
echo.
echo Total    :    %h3%:%m3%:%s3%
echo.
pause

This is a comment/edit to Luke Sampson’s nice timecmd.bat and reply to

For some reason this only gives me output in whole seconds… which for me is useless. I mean that I run timecmd pause, and it always results in 1.00 sec, 2.00 sec, 4.00 sec… even 0.00 sec! Windows 7. – Camilo Martin Sep 25 ’13 at 16:00 «

On some configurations the delimiters may differ. The following change should cover atleast most western countries.

set options="tokens=1-4 delims=:,." (added comma)

The %time% milliseconds work on my system after adding that ‘,’

(*because site doesn’t allow anon comment and doesn’t keep good track of identity even though I always use same guest email which combined with ipv6 ip and browser fingerprint should be enough to uniquely identify without password)

In case anyone else has come here looking for an answer to this question, there’s a Windows API function called GetProcessTimes(). It doesn’t look like too much work to write a little C program that would start the command, make this call, and return the process times.

Another approach with powershell:

@echo off
for /f %%t in ('powershell "(get-date).tofiletime()"') do set mst=%%t

rem some commands

powershell ((get-date).tofiletime() - %mst%)

this will print the execution time in milliseconds.

The answer of driblio can be made a little shorter (though not much readable)

@echo off

:: Calculate the start timestamp
set _time=%time%
set /a _hours=100%_time:~0,2%%%100,_min=100%_time:~3,2%%%100,_sec=100%_time:~6,2%%%100,_cs=%_time:~9,2%
set /a _started=_hours*60*60*100+_min*60*100+_sec*100+_cs

:: Calculate the difference in cSeconds
set _time=%time%

set /a _duration=_hours*60*60*100+_min*60*100+_sec*100+_cs-_started

:: Populate variables for rendering (100+ needed for padding)
set /a _hours=_duration/60/60/100,_min=100+_duration/60/100%%60,_sec=100+(_duration/100%%60%%60),_cs=100+_duration%%100

echo Done at: %_time% took : %_hours%:%_min:~-2%:%_sec:~-2%.%_cs:~-2%

::prints something like:
::Done at: 12:37:53,70 took: 0:02:03.55

To the remark of Luke Sampson this version is octal safe, though the task should be completed in 24 hours.

my code gives you the running time in milliseconds, up to 24 hrs, it is locale insensitive, and accounts for negative values if code runs through midnight. it uses delayed expansion, and should be saved in a cmd/bat file.

before your code:

SETLOCAL EnableDelayedExpansion

for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set t=%%I
set /a t1 = %t:~8,1%*36000 + %t:~9,1%*3600 + %t:~10,1%*600 + %t:~11,1%*60 + %t:~12,1%*10 + %t:~13,1% && set t1=!t1!%t:~15,3%

after your code:

for /f "tokens=2 delims==" %%I in ('wmic os get localdatetime /format:list') do set t=%%I
set /a t2 = %t:~8,1%*36000 + %t:~9,1%*3600 + %t:~10,1%*600 + %t:~11,1%*60 + %t:~12,1%*10 + %t:~13,1% && set t2=!t2!%t:~15,3%
set /a t2-=t1 && if !t2! lss 0 set /a t2+=24*3600000

if you want running time in HH:mm:ss.000 format, add:

set /a "h=t2/3600000,t2%%=3600000,m=t2/60000,t2%%=60000" && set t2=00000!t2!&& set t2=!t2:~-5!
if %h% leq 9 (set h=0%h%) && if %m% leq 9 (set m=0%m%)
set t2=%h%:%m%:%t2:~0,2%.%t2:~2,3%

ENDLOCAL

variable t2 holds your running time, you can echo %t2% to display it.

Having Perl installed the hires solution available, run:

C:\BATCH>time.pl "echo Fine result"
0.01063
Fine result

STDERR comes before measured seconds

#!/usr/bin/perl -w

use Time::HiRes qw();
my $T0 = [ Time::HiRes::gettimeofday ];

my $stdout = `@ARGV`;

my $time_elapsed = Time::HiRes::tv_interval( $T0 );

print $time_elapsed, "\n";
print $stdout;

The following script uses only «cmd.exe» and outputs the number of milliseconds from the time a pipeline is created to the time that the process preceding the script exits. i.e., Type your command, and pipe the to the script. Example: «timeout 3 | runtime.cmd» should yield something like «2990.» If you need both the runtime output and the stdin output, redirect stdin before the pipe — ex: «dir /s 1>temp.txt | runtime.cmd» would dump the output of the «dir» command to «temp.txt» and would print the runtime to the console.

The following script emulates *nix epoch time, but it is local and regional. It should handle calender edge cases including leap years. If Cygwin is available, epoch values can be compared by specifying the Cygwin option.

I’m in EST and the difference reported is 4 hours which is relatively correct. There are some interesting solutions to remove the TZ and regional dependencies, but nothing trivial that I noticed.

A solution using pure PHP for cmd and one env. variable:

@echo off
setlocal enableextensions

REM set start time env var
FOR /F "tokens=* USEBACKQ" %%F IN (`php -r "echo microtime(true);"`) DO ( SET start_time=%%F )

## PUT_HERE_THE_COMMAND_TO_RUN ##

REM echo elapsed time
php -r "echo 'elapsed: ' . (round(microtime(true) - trim(getenv('start_time')), 2)) . ' seconds' . mb_convert_encoding('
', 'UTF-8', 'HTML-ENTITIES');"

• no need for cygwin or non-trusted utilities. Usefull when PHP is locally available

• precision and output format can be easily tweaked

• the same idea can be ported for PowerShell
