I would like to draw attention to probably an overlooked, but actually wonderful aspect of this site. Contests here never start on the hour; in fact, they are always 5 minutes afterwards. Practically all of them start at 17:35, but I've never seen a 17:30. Same thing with 16:05 instead of 16!

While for some users this doesn't matter, personally, it makes a difference for me. I usually time myself to arrive on the hour, and this 5 extra minutes acts as a safety net! In fact, it has saved me several times when I came late, because it psychologically forces me to try to be ready 5 minutes before starting.

Finally, if someone, including administration, could tell me why this practice is mainstream here, I'd be very grateful to satiate my curiosity.

I'd like to know if this peculiar starting time habit means anything to anybody else here. But it's impossible not to think of codeforces whenever the clock reads 17:35 :)
