Are you calling up the viewing of the records by date using a link?

If so, you should be able to add &sb=<fieldnumber>

changing fieldnumber to the number of your time field and then add &so=ascend or descend depending on whether you want the earliest of latest times displayed first.

I'm not positive but you might need to change this to a 'numer' field rather than alpha, but check both ways to be sure.
