What is the use of timezones?
Most people seem to have no idea how timezones work*. It's a couple hours earlier or later somewhere else, but most won't be able to tell you what time it is in any given GMT+n zone.
It's a pain to organise international events online, the best solution I found is link to a live clock and timezone converters. And then there are the people who don't even know what timezone they live in...
*When asking some people randomly, I was surprised by how few could tell me what time it was in GMT-5 (for example) when it's 10PM here (here = GMT+1). The math is simple when first going to GMT and then to the timezone you want: our_time - our_timezone - target_timezone = 18:00 - 1 - 5 = 12:00. It's now 12am, whereever GMT-5 may be. I suppose people just never looked into it, but when they need it they often are like "uh I don't know it works, but if you know it why don't you just convert it to my time?" and you end up converting it all the time for about every participant.
The only reason I can think of why we have timezones, is so the sun comes up at roughly the same time everywhere on earth - in the winter when there is no daylight saving time at least. Or do countries below the equator have DST when it's winter here? Argh.
But my point, why can't we just get rid of timezones altogether and accept the sun goes up at different times? Actually, it already does, it changes from day to day... so there seems to be no point to it at all.
Reading Wikipedia on it, I get where timezones originally comes from and why they were introduced. But nowadays I see no reason not to start using UTC without DST for every country and region. What was 7am in the Netherlands will now simply be 8am. In (what now is) GMT/UTC-8, people will get up at 11pm instead of 7am. Right now it sounds totally weird, but if you are used to it I'm sure there wouldn't be any problem.
It will still be a bit tricky to find the most convenient time for everyone to participate in some online event, but at least 8pm is 8pm. Everywhere.
Am I missing why we are still using timezones, or is it just something that we never got rid of because it's too much work to change?
