I need to determine the exact date / time of a specific tag for a specific module in CVS. Could you help me how can I do this - especially with the eclipse CVS plugin? Thanks in advance.
I do not think you can. Tags in CVS do not exist outside of files that have this tag, and the file either has a tag or not.
That's why it is recommended that you put a label in the tag name when you tag it.
You can apply the same tag to two different files at different times, so trying to find the date / time of the tag is not possible.
