The API converts a time between zones using the rules for that date. The answer includes both local times and their UTC offsets. Same endpoint on every plan, one pooled request per lookup.
QUESTIONS
- Does it handle daylight saving?
- Yes. The conversion uses the rules for the date you choose. If the clocks skip your time, choose another. If a time occurs twice when clocks go back, choose the earlier or later occurrence.
- Why city names instead of EST or PST?
- Abbreviations are ambiguous: CST is Chicago, China, and Cuba. A place like America/Chicago always means one set of rules. The UTC offset shows next to the answer.
- What does +1 day mean?
- The converted time falls on the next calendar day. An evening call from California is already tomorrow morning in Tokyo.
- Can I do this from code?
- Yes. GET /time/{timezone}?to={timezone}&at={time} converts a date and time between zones, including their offsets. One pooled request per call.
