The tz_offset attribute is a float, not an int.

tz_offset: int = 0 should be tz_offset: float = 0.0 as India is at UTC +5.5 hours for example.

self._tz_offset = tz_offset * 60 * 60 can be cast to int if required.

Yeah, having the exact same problem in Australia. There's lots of sloppy timezone code out there that assumes all time zones are aligned to whole-hour intervals. I'll see if I can put in a pull request.
