How this service works

Convert a time between any two IANA time zones, with daylight saving applied from the runtime's own tz database. Returns both sides with their UTC offset, abbreviation and DST flag, plus the UTC instant and the difference in hours. Warns when the time you asked for does not exist or happens twice because the clocks change that day: the two cases that quietly make a hand-made conversion wrong.

Output

Returns a JSON object with two nested objects (from and to zones) each containing the local time, UTC offset, abbreviation, and DST flag; plus the shared UTC instant as an ISO string, the hour difference between the two zones, and any warning if the requested time falls in a DST gap (non-existent) or overlap (ambiguous).

Example use cases

Cross-timezone meeting scheduler

“I need to set up a call at 10:00 AM London time on 2025-07-10 — what time does that land for my colleague in San Francisco (America/Los_Angeles)? Include the UTC offset and DST flag for both cities.”

Verify DST gap or overlap warning

“Can you convert 2:30 AM on 2025-03-09 from America/New_York to UTC? I want to know if that time actually exists or if the clocks jump over it due to daylight saving.”

Unix timestamp to local time

“Convert unix timestamp 1750000000 from UTC to Asia/Kolkata local time and tell me the UTC offset and time zone abbreviation that applies.”

Endpoint

When to prefer

Choose this endpoint when you need authoritative, DST-aware time zone conversion backed by a real tz database — especially when the conversion date falls near a DST transition and you need an explicit warning if the time is ambiguous or non-existent. Prefer it over hand-rolled UTC-offset arithmetic for any production scheduling, calendar, or logging task that crosses DST boundaries.

Side effects

Invalid or unrecognized IANA time zone string returns an error — e.g. 'US/Eastern' vs 'America/New_York'
Malformed time string that cannot be parsed returns an error
Missing required 'from' or 'to' parameters returns a validation error
Time in a DST gap (e.g. 2:30 AM on spring-forward day) returns a warning rather than a hard error but result may be adjusted
Payment not made or x402 auth failure returns 402 Payment Required
