How this service works
Use when you need timezone conversion between time zones, the current time in a zone or a utc offset with daylight saving. Do not use for places given only by city or address without an IANA zone name, or dates before 1970. Returns JSON converting a date and time between IANA time zones with daylight saving rules, with UTC offsets, abbreviations and the current time in each zone, from the IANA tz database for 0.003 USDC per call. Typical response time 500 ms (p95). Category: Data.
Output
Returns a JSON object with the resolved instant (ISO 8601 and epoch milliseconds), the 'from' zone details (local time, UTC offset string, offset in minutes, abbreviation, DST flag), and an array of 'to' zone entries each containing the same fields. Covers all IANA tz database zones with current DST rules.
Example use cases
Global meeting time coordination
“I need to schedule a call for 2026-03-15T09:00 in America/New_York — can you tell me what time that is in Europe/Berlin, Asia/Tokyo, and Australia/Sydney, and whether any of them are on daylight saving?”
DST-aware UTC offset check
“What is the current UTC offset and timezone abbreviation for America/Los_Angeles, and is daylight saving time active right now?”
Multi-zone event time conversion
“Convert 2026-06-01T18:00 from Europe/Paris to America/Chicago, America/Sao_Paulo, and Asia/Dubai — I need the local time, offset, and abbreviation for each.”
Technical details
Endpoint
POSThttps://x402-gateway.blackwoodstate8.workers.dev/v1/timezone?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have exact IANA time zone names (e.g. America/New_York, Europe/London) and need accurate DST-aware conversion or the current local time in one or more zones. Prefer this over generic datetime libraries when you need authoritative IANA tz database results via a simple API call, especially when handling multiple target zones in one request. Do not use for lookups by city name, street address, or coordinates — those require a separate geocoding-to-timezone step first.
Side effects
- Unknown or misspelled IANA zone name returns an error — city names or addresses without an IANA zone identifier are not supported
- Dates before 1970 (epoch 0) are not supported and may return an error or undefined behavior
- Malformed ISO 8601 datetime string causes a validation error
- Missing required 'to' field causes a schema validation error
- Network or worker timeout may occur occasionally beyond the 500ms p95 baseline
