Time zones

Every customer, account and vendor has a Time Zone. The panel shows dates in it, and the days of reports and the billing periods of an account follow it. The Time Zone drop-down lists the 422 zones below, sorted by name.

The XML-RPC API takes the zone as i_time_zone, the ID column below. Read the same list from the switch with getDictionary; see Get system dictionaries.

How a zone is shown

Names are IANA time zone identifiers (Region/City). The switch follows daylight saving time automatically, so no entry has a fixed UTC offset. Country is the ISO 3166-1 two-letter code of the country the zone belongs to.

The zone also sets the date format of the panel: most zones in the Americas show Oct 26, 2026 03:15:00 PM, all others 26 Oct 2026 15:15:00.
