Hey, I am trying to write a script that calculates the time that a batch file takes to run. I have managed to make it print the start and end lines but i want it to be able to calculate the time difference between STT and ENT. If someone could please give me an example of how to do this id me much appreciative. here is what i have so far: ___________________________________ Start Of Batch ___________________________________ @ECHO OFF COLOR F2 ::Set Start Time SET STT=%time% ::Place For Script. ::Set End Time SET ENT=%time% ECHO.%STT% ECHO.%ENT% ___________________________________ End Of Batch ___________________________________ Its obviously a simple script but i am going to add it to another script to log the time it takes to complete. Thanks.

Holla already did the work. ==================== @echo off & setLocal EnableDelayedExpansion If %1a==a goto Usage set starttime=%time% call :ExtractHMSHn %starttime% StartTimeInNum call %* set endtime=%time% call :ExtractHMSHn %endtime% EndTimeInNum :find the Difference in time set /a diff = %EndTimeInNum% - %StartTimeInNum% Set /a Elapsedhrs= %diff% / (60 * 60 * 100) Set /a Elapsedmin= (%diff% - (%Elapsedhrs% * 60*60*100)) / 6000 set /a elapsedsectmp= %diff% - (%Elapsedhrs% * 60*60*100 ) %% 6000 set /a elapsedsec= %elapsedsectmp% / 100 set /a elapsedhun= %elapsedsectmp% %% 100 Echo Elapsed time: %Elapsedhrs%:%Elapsedmin%:%elapsedsec%.%elapsedhun% goto :EOF :Usage Echo Usage: %0 YourCommand [Your command's parameters] Echo Example: %0 ping -n 2 127.0.0.1 echo - will execute "ping -n 2 127.0.0.1" and tells how long it for execution. goto :EOF :ExtractHMSHn set t1=%1 set hun=%t1:~9,2% set sec=%t1:~6,2% set min=%t1:~3,2% set hr=%t1:~0,2% :Remove zero from the begining so that it does not crib about invalid octal if %hun:~0,1%==0 set hun=%hun:~1,1% if %sec:~0,1%==0 set sec=%sec:~1,1% if %min:~0,1%==0 set min=%min:~1,1% if %hr:~0,1%==0 set hr=%hr:~1,1% set /a %2 = %hun% %% 100 + %sec% * 100 + %min% * 60*100 + %hr% * 60*60*100 exit /b endlocal ===================================== If at first you don't succeed, you're about average.

Call me lazy but I just use ntimer.exe from one of the windows resource kits(2003 I think).

Thankyou All very much for your replies. The first one wasn't exactly what i was after but it was what i was looking for for one of my other programs. The first one seems to be a replacement for ntimer.exe. Thanks again, LEoH EDIT: In the second one the last little section has a pause. That is a great idea to show messages for a small amount of time. I never thought about doing that. Thanks for the idea.
