History files - cvs administration

[Brusset, Mathieu]

Hi Everybody,

I'm currently looking forward in CVS maintenance.
I'm currently using CVSNT 1.1.11.3 with winCVS 1.2.

I'm looking for some information about the CVS history file format

For example :

From my history file
Date            user name
M3ce94b73|brussetm|<remote>|baseline0|1.2|test7.asp
 I understand the meaning of some of them but, I don't know how the date is crypted ...

How could I get information about each field of this history file? Is it possible to add more information in it ??

My goal is to be able to answer question as:
What tags are in my repository ?
Who have done what ?
Which files are contained in a given tag ?
And stuff like this ...

Thanks
