Hi,
I wonder if anyone can help....
I am struggling to understand the representation of timedelta when used in
conjunction with astimezone.
Given the code below, in a python interactive interpreter, I am trying to
calculate a resultant datetime an hour earlier from a UTC datetime....
```bash
>>> dt = datetime(2021, 8, 22, 23, 59, 31, tzinfo=timezone.utc)
>>> hour_before=dt.astimezone(timezone(-timedelta(seconds=3600)))
>>> hour_before
datetime.datetime(2021, 8, 22, 22, 59, 31,
tzinfo=datetime.timezone(datetime.timedelta(days=-1, seconds=82800)))
```
I cannot understand why the resultant datetime.timedelta is days=-1,
seconds=82800 (23 hours) .
Why is it not an hour earlier as seconds=-3600? Why is days = -1 when the
resultant calculated date is the same, year, day, month??
