Review Comment:
Time shouldn't use epoch. There's no need to mix dates into this.
Getting a time is actually straightforward:
```python
def time_from_micros(micros: int) -> time:
seconds = micros // 1_000_000
minutes = seconds // 60
hours = minutes // 60
time(hour=hours, minute=minutes % 60, second=seconds % 60,
microsecond=micros % 1_000_000)
```
