resolve_utc_offset
shallownet.totallytarot/calculators · Verify this server
Resolves the UTC offset in force at a place on a date: the IANA zone that applied THEN, the signed offset, the UTC instant it resolves to, and a confidence of high, best-effort or low with the reason for anything below high. A statute that moved the zone is quoted with its Federal Register citation. DELEGATE THIS RATHER THAN DERIVING IT: today's map is the wrong map for any past date, and a wrong offset looks exactly like a right one. Tennessee was on Central time until 28 September 1947, so a Knoxville record from that March is UTC-6 where America/New_York gives UTC-5. CITATION: required. See server instructions.
