Supplying Time Zones
You can specify timezone input parameters to the pub.datetime services in the following formats:
As a full name.
For example: Asia/Tokyo America/Los_Angeles
You can use java.time.ZoneId.getAvailableZoneIds. () method to obtain a list of the valid full name time zone IDs that your JVM version supports.
As UTC.
For example: UTC - 5h
As a custom time zone ID, in the format GMT[+ | -]hh[ [:]mm].
For example: GMT+2:00 Time zones 2 hours east of Greenwich GMT-3:00 Time zones 3 hours west of Greenwich (that is, Argentina Standard Time and Brazil Eastern Time)
GMT+9:30 Time zones 9.5 hours east of Greenwich (that is, Australian Central Time)
As a three-letter abbreviation.
For example: PST Pacific Standard Time
Important:
Because some three-letter abbreviations can represent multiple time zones (for example, "CST" could represent both U.S. "Central Standard Time" and "China Standard Time"), all abbreviations are deprecated. Use the full name, UTC, or custom time zone ID GMT formats instead.
