In SQL you can do a DATEDIFF...I'm not in front of postgresql so am not
sure if it supports this.
Syntax is
select datediff (day, mydate, 'Jan 10 1999'
from table
If mydate = Jan 9, then the result is one. I think datediff accepts
datetime, so if you specify it properly (i.e. '1 Jan 1999 10:05") then
you'll get the right answers. Just change day to whatever you need.

Mark.
