Help with editing Minutes section in Ploneformgen Data/Time Field

Hi All,

I have a Date/Time Field on one of my forms built using Ploneformgen. I am trying to add a timestamp like '1990/May/24 11:07 AM' but i find only multiples of 5 provided in the minutes section of the field. Please let me know how to make date/time field show all minute values from 00 to 59.
