Question

We have a CVS repository and we create a tag on the active branch whenever a successful build is done.
Is there any way by which I can determine the date when the tag was created?
Looking into the history doesn’t helps since it only tells the date-time stamps of the file when it was modified.

Thanks!

You can easily configure CVS to log all tag-related actions.
In the file ‘$CVSROOT/CVSROOT/taginfo’ you can hook up a
pre-tag script like this:

ALL $CVSROOT/CVSROOT/do_tag

If this script returns a non-zero exit value, the tag operation will
be aborted. This allows for syntax checks on the tag names. You can
also use this hook to send emails, whenever a new release has been
tagged. To write a history of all tag operations, you need to do
something like this in your do_tag file:

#!/bin/sh
TAGHISTORY=~cvs/taghistory.log
echo -n "$(date): user $USER, tag " >> $TAGHISTORY
echo "$*" >> $TAGHISTORY
exit 0

If you have the history function enabled, you can execute
the following command:

cvs history -a -T

It will give you some lines like this, giving you date+time, user, module and tagname of each tagging operation:

T 2011-04-02 07:55 +0000 ralph  mylib [testtag:A]
