[horde] How do I log the last login time information?

[Liam Jewell]

Hello, I'm new to the list so please bear with me if I've posted this to the
wrong place.  I'm looking for a way to log the "last login time" information
that is displayed upon logging in, into some sort of text file which I can
retrieve later.   I am a relatively novice user, so any descriptions of how
to do this should be in some form of English, not geek :-D.

Thanks for your help in advance,
Liam
