cvs log and date ranges

[Zachary M. Smith]

I am trying to use 'cvs log' to show me the log entries for files
that changed between two dates.  So, for example, I run the following
command:

cvs log -d'05/29/2001 03:01>05/29/2001 12:06'

which I would expect to show me the logs for all the files changed between
3:01am and 12:06pm on May 29.

i've also tried the folowing:

cvs log -d'2001-05-29 03:01>2001-05-29 12:06'

but what i get is *all* of the changes.  i am not getting a range.

Now, what I'd really like to do is pass log to tags and find the differences
between those, but I have not seen any info on how to do that so i'm trying
to make due with dates.

Any help is appreciated.
