It's not so weird, because the question "what time is it?" has a single authoritative source, and it can only be answered by a single authoritative source. (NIST in the US, right?)
But the question "when should we go to work?" doesn't have a single authoritative source, it all depends, it's all culture, it's all customs, everyone is free to do their own thing, but protestant work ethic bla bla bla, and here we are with most people starting work at 9, and if you don't, you're a weird slacker.
Yes, agreeing to start work at 10 in the winter is completely functionally equivalent with moving the clock forward an hour during winter, but it's just mentally impossible to implement because humans are weird like that.
