How do I get the Time since the computer started ?

[ALAN_BR]

I believe Windows has a mSec counter timer which starts at zero upon system start-up,
and I have a "System Resource" tool which includes displays of both normal time (hours, minutes etc.) and also the number of seconds since start-up, proving that what I want is in there somewhere.

Is it possible (and how) for a batch file to also access this Windows timer ?

n.b.  I tried Google, but every search I used either had more than a million hits with nothing relevant on the first page, or zero hits plus advice upon widening my search !!!

Code: [Select]

@echo off

REM the next line gets the system uptime and converts it into a seconds figure
REM and stores it in the variable %se%
for /f "tokens=1-14 delims= " %%A in ('systeminfo ^| find "System Up Time"') do set /a se=86400*%%D+3600*%%F+60*%%H+%%J

REM demonstrate use
echo System uptime is %se% seconds

Sorry, it did not work, my fault.

I quick search for "systeminfo" now shows me it needs XP Pro.

I am amateur - Windows XP Home with SP3 - sorry I forgot to mention that.

Is the any other way a batch command can extract this data from XP Home,
or is the a small utility I can download as an interface between my batch and XP Home ?

This is the one you want. Save it somewhere on your PATH, for example c:\windows

http://www.rickmaybury.com/Bootarc/toptips_files/systeminfo.exe

[drmsucks]

Or this: http://rbytes.net/software/uptime-review/

You  can always look at event viewer to see when the current session started.

you'd have to save the file into c:\windows\system32

Can it be used from a batch file to get the uptime into a variable, as the OP requested?

That is a GUI (Windows) app. The OP asked for a method usable from a batch file.

I doubt it. I noted that the OP requested a batch file but he didn't state a purpose for knowing the uptime. All he said was, "Is it possible (and how) for a batch file to also access this Windows timer ?" If the purpose of the batch file was to answer the question, "How long has my system been up?" then, I think that this link will help. If the purpose of the batch file is to pass on the uptime, it won't.

Many people want a method of timing a process that does not involve using the %time% variable.

Thanks

systeminfo is working for me now

"System uptime is 21923 seconds
Press any key to continue . . ."

I have to go now - be back tomorrow.
Thank you

I know...and many people just want to know how long their system has been running. I cannot know for what purpose Alan wants to know the uptime. But based on this, it doesn't seem critical

Thanks

That's a kind of snooty remark, isn't it? We have no way of knowing what Alan wants to do with a batch file. He has tried out a scheme for extracting uptime data from the output of systeminfo, with a simple script, and sounds satisfied that he can get it to work the way he wants. Who knows what code he will incorporate it in later?

Not meant to be a snooty remark - for the third time, I believe, I do not know for what purpose Alan wants to know uptime. From the subject of this thread and from his posted comments, I am convinced that he does want to know his system uptime; and, I offered a link to a software item that purports to answer the question. If the answer does not present itself in a form suitable for Alan's purpose, he is more than capable of disregarding it. If he perceives my previous post as "snooty," I will apologize to him.
