is an option for DateObject, DateString, and related functions that specifies the time zone to use for dates and times.

Details

The TimeZone option is typically used to specify the time zone associated with a given date or collection of dates.
Possible TimeZone specifications include:

	n	number of hours added to GMT
	"zone"	named time zone
	Entity["TimeZone", "zone"]	time zone specified by the "TimeZone" entity
	loc	time zone associated with the given location
	Automatic	automatically determine the time zone
	None	specify no time zone information

For numeric values of n, TimeZone->n specifies that results should be returned for a time zone in which n hours must be added to Greenwich Mean Time (GMT) to obtain local time.
TimeZone->"zone" specifies that results should be returned using the appropriate offset for the named time zone "zone" on the appropriate date.
Example time zone strings include "America/Chicago", "Europe/London", "Asia/Tokyo", "Zulu", "-04:00", "GMT+05:45", etc.
A list of available time zone entities can be found using EntityList["TimeZone"].
TimeZoneloc will use the time zone associated with the specified location Entity or GeoPosition loc.
TimeZoneAutomatic indicates that the time zone value should be determined automatically, defaulting to $TimeZone if no time zone information is otherwise available.
TimeZoneNone indicates that no explicit time zone information should be inserted, defaulting to $TimeZone in cases where time zone offset instantiation is necessary.
The typical default setting is TimeZone:>$TimeZone.
