not alf but I can answer - what I did was simply changed the template to show the time hours for the day 1, 2, 3am etc followed by 12, 1, 2, 3, 4 pm etc...
To get actual REAL times times not just time place holders would require you to change the template more and to actually modify the area for time to be something like UHrx...where X is the time slot..but you can only go to 8 time slots (as far as I can tell.)
