[Blaine Lang]

Will we still not need Library functions then to compare dates in code as I 
think you need to convert the YY-MM-DD HH:MM:SS Date/time format strings to 
UNIX Timestamps for comparison in code - correct?

Or did I read that you can request Propel to do this converstion when 
retrieving the field?

TIMESTAMP in Propel == DATETIME in MySQL. So in mysql DDL you'd want
to use DATETIME.
