Common mistakes when calculating time differences

Watch out for these common errors:

  • Forgetting that DST changes the UTC offset. Seattle is currently in DST, and Atlanta is currently in DST. The time difference may change when DST transitions occur.
  • Assuming the time difference is always a whole number. Some timezones use 30 or 45 minute offsets.
  • Confusing which city is ahead and which is behind. The city further east is always ahead in time.
  • Using fixed offsets instead of IANA timezone identifiers. Fixed offsets do not account for DST.
