Which is the exact period for the hourly weather records?
WIth the hourly timeline we get hour points 0-23.
The period length is expected to be 1 hour. But how should we treat the 'datetime', as a start, end or a center point of 1-hour periods?
E.g. Considering the record with datetime = 01:00
- Datetime as the start point, covers the period of 01:00 - 02:00.
- The center of 1-hour period: 00:30 - 01:30
- The end of the period: 00:00 - 01:00.
Which one is correct?
