What's Changed
- Python datetime object comparisons and math don't work as expected when the objects are aware and have the same tzinfo attribute. Basically, the fold attribute is ignored in this case, which can lead to wrong results. Avoid this problem by using aware times in UTC internally. Only use local time zone for user visible attributes.
- Also, use HA's local time zone instead of the OS's time zone.
