Yes, it would be a lot easier... But I can't do that, because the time fields are default values; i.e. the time is the same every week but not the date...

You could possibly do it without, using some logic like this:
1. compute MAX(time) - MIN(time)
2. if less than 12 hours, assume no midnight wraparound, sort by straight time.
3. if more than 12 hours, assume a wraparound, sort accordingly.
But it seems a heck of a lot easier and less error-prone to store
a full timestamp instead. What's your motivation for storing only
time, anyway? Not space savings --- the time and timestamp types
are both 8 bytes in PG.
