Store render time as DateTime<FixedOffset>

Since version 0.25.0, PyO3 can't convert `DateTime<Local>` to
`PyDateTime` anymore. Because of that we now convert the chrono
`DateTime<Local>` to a chrono `DateTime<FixedOffset>`. This fixes the
`PyDateTime` conversion, since PyO3 does support converting
`DateTime<FixedOffset>`.
