List time zones

Description

timezones displays a list of all Internet Assigned Numbers Authority (IANA) time zones accepted by the datetime function. For each time zone, the list includes the offset from UTC (in hours, where east is positive) and the daylight saving time shift (in hours).

timezones(area) displays a list containing all IANA time zones in the specified geographic area.

example

T = timezones(___) returns the list in a table.

[T,vers] = timezones(___) also returns the IANA Time Zone Database version currently used by the datetime data type. This version includes recent updates from the IANA. For more information, see IANA Time Zone Database.
