[turba] Question about database entries

[Michael Richey]

First of all, I'd like to congratulate the creators of horde and turba. 
I had previously implemented Squirrelmail, which is a fairly nice IMAP
client...but then I found horde, imp and turba and I'm totally blown
away.  Excellent job!

The short of my problem is that my Squirrelmail implementation did not
play nicely with the existing imap server.  After 2 months of running,
it would randomly lock mailboxes and refuse to connect (I believe this
to be a limitation of the imap server, but can't prove it yet), so I
decided to try horde out because I needed a solution yesterday. 
Horde/imp/turba works great and I'm very pleased with the results.

Ok, here's my question.  I'm using MySQL database back end for
everything.  Turba assigns an ID for each address book object, and I'm
wondering how these ID's are generated.

I've got several thousand address book entries for all of my users and
am working on a method to import all of them at once.  I'm concerned
about that ID though.  Is it special?  Will I let out the blue smoke if
I just generate unique 32 character ID's based on timestamp?

Anyway, hopefully I'll discover the answer while browsing the code....if
anybody has a quick answer to save me some time, I'd appreciate it.
