Pardon me for jumping in here, but aren't timestamps supposed to be returned 
as longint? They should like something like 1184670240 = Jul 17, 2007 @ 
11:04:00. Whenever I worked with timestamps, I had to write a class to 
convert either way. I understand mysql can convert as a sql command. I 
found this on the web: 
http://dev.mysql.com/doc/refman/5.0/en/date-and-time-functions.html
which has a number of functions dealing with conversions.
