why does this script work when executed as user, but not when executed as system account

Need to deploy script, which gets deployed with system account.

To test, running the attached code and when executed as a user... works fine.  

To further test, running the attached code as SYSTEM account (by running new command prompt via 'at 01:23 /interactive cmd.exe')... does not work.  Results in "The syntax of the command is incorrect".

Found out the %today% variable is what's causing the problem.  However, it's only a problem when running it as the SYSTEM account.  Why is this??
@echo off
set today=%date:~-4%%date:~4,2%%date:~7,2%
 
rename C:\test.log %today%_test.log

Open in new window

I imagine you will find the default system date is set to a different date format.  Try

echo %date%

then you will either have to change the system locale using the "set default" button in regional options (or wherever it is in xp/vista never looked) or change the parts of the %date:~ etc. to be the different parts of the string.  At the moment it takes:

the last 4 chars (year), from 4th char for 2 (month?), then from the 7th char for 2.

I imagine it has no Day component at the beginning so it will end up with a / character in the filename you are making?
Try:
set today=%date:~-4%%date:~0,2%%date:~3,2%

when, in the SYSTEM cmd prompt, I run

echo %date%

I get --> Fri 04/03/2009


Tried

set today=%date:~-4%%date:~0,2%%date:~3,2%
rename C:\test.log %today%_test.log

and although that (also) worked running as regular user, I got the same problem when running it as SYSTEM... ??

Glad it helped... not sure how if the system cmd.exe returned date with DDD dd/mm/yyyy etc. but heh as long as it works for you!
