We would like to inform you that The State of Palestine has adopted the first part of the specification for its time zone.

and linked a document which states in part:

Names normally have the form AREA/LOCATION, where AREA is a continent or ocean, and LOCATION is a specific location within the area.

The State of Palestine is the Palestine Time Zone owner, It has the sole right to set, modify and register the Standard Time Zone; Name / Database / DST.

The Time Zone Database includes two zones related to Palestine, with the identifiers "Asia/Gaza" and "Asia/Hebron". These zones differ for (recent) historical reasons, because the rules for summer time (daylight saving time) varied during the period from 2008 to 2012. The file "asia" in the TZDB has comments which explain the exceptions for Gaza. By stating:

Palestine will use Palestine Standard Time (PSST), and Palestine daylight time (PSDT).

the PSI document appears to signal that the entire State of Palestine will observe a single changeover date and time, and will no longer observe different changeover dates in Gaza. However, for historical reasons involving the 2008–2012 daylight time discrepancies, both zones will continue to be reflected in TZDB. The TZDB administrators will retain the right to keep the identifiers "Asia/Gaza" and "Asia/Hebron", or to change them according to rules that they and the larger community have established. Governments or other bodies do not determine these identifiers, and cannot unilaterally claim the right to do so. -- Doug Ewell, CC, ALB | Lakewood, CO, US | ewellic.org
