I, as a general user, would like to add a bit information to the other user's comment.
Name of zone in the tz database is not decided according to name given to a timezone nor is it given to name of a country's capital. Instead it is named after the most populated city in each zone.

Also, according to my understanding, West Bank and Gaza is separated in these record because their history of time zone is now exactly identical from year 1970 onward, which the database is trying to keep record of history of each and every time zone in existence since year 1970. If you find there are error on time-keeping history regarding Palestine in the database then please submit relevant information to the list for correction of those records.

,Dear Sir
.I’m Heba Hamad .I have been appointed as a focal point by the Ministry of telecommunication and information technology (state of Palestine) to communicate with you

I’m contacting you in regard to the time zone data base the field related to the state of Palestine. I checked the published data regarding the time zones related to Palestine and noticed that it’s not accurate, and hence I would like to ask for an update to the time zone data base related to Palestine to be as follow 

  PS   State of Palestine   Asia/AlQuds       UTC +2:00

:Instead of the following data 
 PS          State of Palestine            Asia/Gaza                        UTC +2:00
 PS          State of Palestine            Asia/Hebron                    UTC +2:00
 

.Kindly advise if any documents, information or procedures are needed from our side

 

,Best Regards
