Edge cases & notes
  • DST gaps/overlaps: Some local times don’t exist (spring-forward) or occur twice (fall-back). PHP normalizes these.
  • Half-hour / 45-minute offsets (e.g., India +5:30) are supported; the difference can be fractional (e.g., +5.5h).
  • IANA vs city names: Use canonical IDs (e.g., America/Phoenix) rather than generic terms (e.g., “MST”).
