How this service works
Broker-Zeit und UTC umrechnen. IANA-Zeitzone zwingend; doppelte Ortszeit nur mit ausdrücklich geliefertem fold, nicht existierende Zeit wird abgewiesen. Alle Zahlen, Kurse und Vorgaben liefert der Aufrufer. Keine eigenen Kursdaten, kein Brokerzugriff, keine Ausführung. Rechenwerkzeug, keine Anlageberatung, keine Empfehlung.
Output
Returns the converted timestamp in the target timezone (either UTC or broker local time), correctly accounting for IANA timezone rules, DST transitions, and explicit fold disambiguation. Non-existent local times (e.g. during spring-forward gaps) are rejected with an error.
Example use cases
Pre-market session UTC alignment
“I need to convert the broker's market open time of 09:30 on March 10, 2024 in America/Chicago to UTC — can you do a broker_to_utc conversion for me?”
Reconcile trade timestamps from UTC logs
“I have a UTC timestamp of 2024-06-15T13:45:00Z and I want to know what local broker time that corresponds to in Europe/London — please do a utc_to_broker conversion.”
Handle DST fall-back ambiguous hour
“Convert 02:15 AM on November 3, 2024 in America/New_York from broker time to UTC — this is during the clock-fall-back overlap, so use fold 1 to indicate it's the second occurrence of that time.”
Technical details
Endpoint
POSThttps://handel.halowerk.com/v1/rechner/timezone?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need precise, rules-compliant conversion between UTC and a financial broker's local timezone, especially when DST transitions or clock-overlap ambiguities must be handled correctly. It is ideal for trade timestamp reconciliation, session scheduling, and any workflow where incorrect timezone handling could cause compliance or operational issues. It does NOT provide market data, execute trades, or offer investment advice.
Side effects
- Invalid or non-IANA timezone string returns an error
- Non-existent local time (e.g. during DST spring-forward gap) is rejected
- Missing required fields (mode, time, timezone) cause a validation error
- Ambiguous local time without an explicit fold value may be rejected or flagged
- Malformed time string (wrong format or length) causes a parse error
