Why the pretentious zero?
 

What's the point of the zero in 01:24 PM? I guess this is just a pet peeve of mine. I think in 24hr time. When I see 01[anything] my brain automatically assumes it's 01XX. If you're going to use AM/PM what's the point of showing the zero? I can't think of a single good reason, even among gamers. 3/4 of the hours have a single digit when you're using AM/PM so why tack that annoying zero on there?

Oh yeah, tech support issue: Please let me view the times in 24hr. AM/PM is silly.

Thanks.

Dunno. Why the colon?

For myself, I find it easier to read. I like all my dates to have the same size. But that's just a personal thing.

Actually... I wonder if maybe the zero dates back to the old seven segment LED displays (and incandescent public versions showing time). In those cases a blank digit is still visible and looks like a failure.
