Windows 7 REG ADD and %DATE%

I need to write a Date stamp into the registry from a .BAT script. I've tried the following examples but no luck so far...

reg add hklm\software\test /v datestamp /d %%DATE%% /t REG_EXPAND_SZ /f

reg add hklm\software\test /v datestamp /d %DATE% /t REG_EXPAND_SZ /f

reg add hklm\softwa开发者_如何学Pythonre\test /v datestamp /d ^%DATE^% /t REG_EXPAND_SZ /f

Can someone point me to how this can be done properly? Thanks!

If the date format is already OK, just add quotes:

reg add hklm\software\test /v datestamp /d "%DATE%" /t REG_EXPAND_SZ /f
