Thanks @codephage2020 and @sdf-jkl -- this looks great to me, except for one question (on returning Option). Let me know what you think

…tampType (apache#9337) Add two new methods to the ArrowTimestampType trait: - from_datetime: creates a timestamp from a timezone-aware DateTime<Tz> - from_naive_datetime: creates a timestamp from a NaiveDateTime with optional timezone This simplifies the conversion path from DateTime<Tz> to i64 timestamp, avoiding the need to manually call .naive_utc() + make_value(). Both methods return Option<i64> to safely handle overflow (e.g. nanosecond precision with extreme datetime values). Uses checked arithmetic consistent with existing make_value implementations. Includes tests for UTC, fixed-offset, subsecond precision, DST ambiguity, non-existent local times, and overflow boundaries.
