Question : How do I get the Date() to begin at 07:00 instead of 00:00

I have two fields with date and time in them.
The date defaults to the Date() and time default to Now().
However, I want the date field Date() to begin at 07:00 instead of 00:00 so that the time between 00:00 and 06:59 has the previous date instead of today's actual date and
 switches to the new date at 07:00. The time will always default to correct time or Now().
I was wondering if the best thing to do would be use the Now() function and subtract .2916667 (7/24) to get the date offset?

Is your date field just for display purposes? If so you could just use one field containing date/time and calculate the modified display date for as you have suggested. The time suppressed by the display formatting options.
