historicalTimeZones

Type: JadeTimeZoneByYearDict

The read-only historicalTimeZones property of the JadeTimeZone class contains JadeTimeZone objects that represent historical time zone information for years in which that information exists. During these years, Coordinated Universal Time (UTC) bias and daylight saving rules were observed that differ from the rules currently observed.

These historical time zones are stored as values in the JadeTimeZoneByYearDict class and which themselves have an empty JadeTimeZoneByYearDict; that is, they have no keys or values. (All JadeTimeZone objects must have a historicalTimeZones property, but JadeTimeZone objects that represent historical time zones do not themselves have historical time zones so their historicalTimeZones dictionary is left empty.)
