Ok, now I am really just confused! I tried to change it to 12.15 and 1.00 and it made the 12.15 to 3:30AM

SO from now on, instead of 12:15 I should write in 12.25 to mean the same thing? Won't that be confusing? Ooo... and now I'd have to type in 13.00 for 1:00, right?

Now I really do feel like a moron! Considering how much trouble I can see me having typing in time on the 24 hour format and using decimals instead of the time, I might be better off sticking to manually entering info - I'll enter in just as many typos trying to convert to 24 hours and decimal
