Implemented for the next release: https://feedback.objo.dev/feature/393
Objo now has a TimeZone class with TimeZone.Current, TimeZone.UTC, TimeZone.FromIdentifier(), identifier validation, available timezone identifiers, UTC offsets, daylight-saving checks, invalid/ambiguous local-time detection, and explicit conversion between timezones.
DateTime remains a timezone-naive wall-clock value for compatibility. TimeZone is used when you want to interpret or convert that DateTime in a specific timezone, which avoids hidden local-machine assumptions around DST and Unix timestamps.
