Time Zone Converter

Time Zone: a planned Super Calculator tool. Covers source date and time (datetime). Stub page: the tool, its formula and a worked example are not published yet.

Time Zone Converter is a planned calculator in the dates and time section of Super Calculator, covering dates and time.

What this calculator will compute

Inputs: source date and time (datetime), source zone or city (IANA id) and target zone or city (IANA id).

Outputs: target local time (datetime), UTC offset difference (h), day shift (n) and DST in effect (bool).

Formula, recorded as scope and not yet verified against a primary source: Convert a local wall time in IANA zone A to zone B by resolving both to UTC using the tz database offset in force at that instant, including the daylight saving rule for that date. Never use a fixed offset: the offset for a zone is a function of the instant, not of the zone alone.
