How this page is calculated
Offsets and daylight-saving rules come from the IANA time zone database through the standard Intl API — the same source the board uses, so nothing here is a hand-written offset table. Working hours are 09:00–18:00 local on both sides unless you change them on the board. City names and coordinates: GeoNames (CC BY 4.0).
