I just had to coordinate an online meeting with some guy at a company, I had no idea where he's based but he suggested time slots in EST (I'm in Toronto). I asked him twice if he's sure, thinking he may be based outside of North America and doesn't know that Toronto currently follows EDT which is GMT-4h, and he just responded "Eastern Standard Time".

And of course he actually meant EDT. Turns out he is based in North America, just dumb.

Fuck timezones, but more than that fuck daylight saving time. You want an extra hour of sunshine after work in summer? Shift the work schedule, not the fucking clock!
