Batch file not working as a scheduled task

[David]

Not strictly a command prompt problem I know, but not sure where else to look.

Running Windows 2000 SP2

The batch file works just fine when started outside of the scheduled
tasks, but when run as a scheduled task it fails.
I believe it is a problem with the Command Extensions - ie. my batch
file is using them, and they are not enabled. I get the following
errors :

'date /t' is not recognized as an internal or external command,
operable program or batch file.
'time /t' is not recognized as an internal or external command,
operable program or batch file.

The lines are :

for /f "tokens=1,2,3,4* delims=/ " %%K in ('date /t') do set day=%%L &
set month=%%M & set year=%%N
for /f "tokens=1,2 delims=: " %%T in ('time /t') do set hour=%%T & set
minute=%%U

It's an inherited script, and I have evidence of it working in the
past. I have a suspicion that SP2 has been applied since that time.

The ultimate goal is to rename a file with a time and date included
before archiving it. If there is an alternative way then I'm more
than happy to ditch what I've got now!!

TIA
David.

You can turn them on by adding 'setlocal ENABLEEXTENSIONS' to your
batch file, something like:-

@echo off & setlocal ENABLEEXTENSIONS

The method you're currently using to load date and time components into
variables is highly reliant the regional settings and delimiters used.
This is definitely not a good idea especially if the script is to run
on other machines. Here's a more reliable way (but I'm not your dad <g>)

01. @echo off & setlocal ENABLEEXTENSIONS
02. call :GetTime h n s t
03. call :GetDate y d m
04. echo/Today is: %y%-%m%-%d% %h%:%n%:%s%
05. goto :EOF

That's right extensions are not enabled. Make sure these reg values are
set to 1

HKEY_USERS\.DEFAULT\Software\Microsoft\Command Processor\EnableExtensions
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Command Processor\EnableExtensions

If the task was running under a user account (as opposed to the system
account) then logon as that user and check this value:-

HKEY_CURRENT_USER\SOFTWARE\Microsoft\Command Processor\EnableExtensions
