How can I Tag a module based on a particular Date?

[A.P.]

Hi.
How can I Tag a module based on a particular Date using WinCVS?

I tried using the Create a Tag By Module menu option under Create Menu but
it isn't creating the tags for.

My Repository has some files modified post Feb 25th. I wish to tag them all
on their Feb 25th state.

Any help in these directions would be helpful..

Thanks.
