I just noticed a bug in my twtxt client's twt publish form – luckily just before submitting. Why on earth make it most programming languages so easy to misuse their damn date time APIs!? On today's episode we have Python's `datetime.datetime.utcnow().replace(second=0, microsecond=0).astimezone().isoformat()` which is not what we want, it's actually `datetime.datetime.now(datetime.timezone.utc).replace(second=0, microsecond=0).astimezone().isoformat()` instead. The former gives us the time in UTC and thus is off by an hour in my case: `2021-01-03T23:30:00+01:00` vs. what I'm really after: `2021-01-04T00:30:00+01:00`
