How can I set multiple users regional settings (time zones)?

Question

Hi all,

I'm trying to work out how to so set multiple users regional settings (time zones) in MOSS 2007.

Is there a way that I can do this myself on behalf of the users? Or will the individual users need to do it themselves on a site collection basis by going to "My Profile" then "My Regional Settings", un-ticking "Always follow web settings" and selecting their time zone?

I know that in 2010 this can be done in the user profile service application - is there a similar way in 2007?

Thanks.
