adding dates to a filename in a bat script

In case others out there need something so prehistoric as making a bat script which adds a date to a filename for ex when creating a back up with 7-zip.

The following worked for me:

call "c:\Program Files\7-Zip\7z.exe" a -tzip %date:~6,4%-%date:~3,2%-%date:~0,2%.%time:~0,2%-%time:~3,2%-zipFile.zip *.dll


will zip files into an archive called:


2010-06-04.15-37-zipFile.zip


Hope it will save you some frustration!
