KDE desktop has a clock

but I could not find the name in the Show Timezone -> configure zone
of the clock. How can I do this?
Thanks

From the 'asia' source file in tzdata.2007e that is used by virtually all
UNIX systems to create the zone files:
Yemen
# Zone NAME GMTOFF RULES FORMAT [UNTIL]
Zone Asia/Aden 3:00:48 - LMT 1950
3:00 - AST
Saudi Arabia, Kuwait, Bahrain, Qatar, Yemen use the same time zone, which
the source file unofficially calls 'Arabian Standard Time (AST). The other
zonefiles in this group are 'Asia/Bahrain', 'Asia/Kuwait', 'Asia/Qatar' and
'Asia/Riyadh'. Daylight Saving Time is not used.

The time zones are listed in /usr/share/zoneinfo files and directories, and
the only Mideast one is Riyadh, but there are lots of "mideastern" ones in
Asia. Aden,Riyadh Amman,Jerusalem, Damascus, Dacca, Baghdad,Bahrain,Dubai,Gaza,
.... so that probably means that noone has
written on for Sana or that Sana does not differ from one of those. (Eg, what is the difference in timezone between Sana and Aden?) In the latter
case It would be a mistake to make separate identical tz files for each and
every political entity in the world. However, if the Sana time zone is
really different in some way ( present or past) from that of one of those, and if
you know how it has worked, then write a time zone file for Sana and submit
it for inclusion in tzdata.
(For example the Aden time Zone data is
Zone Asia/Aden 3:00:48 - LMT 1950
3:00 - AST
Which says that until 1950 Aden kept Local Mean Time ( Ie mean sun time)
which was 3 hours and 48 seconds before GMT, and thereafter it kept AST
which was 3 hours before GMT.
Is Sana different? (Well, its mean solar time would probably have been
2:56:44 rather than 3:00:48-- that should be 3:00:08 if one believes the
lattitude on googleearth--but you are probably not really interested in the
situation prior to 1950.)
(download the tzdata file and look at the entries for some of the other
cities.) You should have some authoritative sources for your historical
information.

Or that the apostrophe in the city name goes against the naming scheme
used - see the 'Theory' file contained within the tzcode2007?.tar.gz
file. While Sana'a is more populated (~950k) than the second (Aden,
~400k), third (Ta'izz, ~320k) or fourth (Al-Hudaydah ~300k) largest
cities, Aden is more well known, and fits the character set used. Also,
Yemen (as opposed to the "Protectorate of South Arabia" which became the
Yemen People's Democratic Republic with a capital of Aden, and _later_
merged into the present 'Yemen') did not have an official "standard"
time at least through 1975 (source: National Geographic Atlas of the
World, 4th Edition, 1975), whereas US Hydrographic Office chart 5192,
1958 edition shows the Aden named zone. This matter is also discussed
in that 'Theory' file.

Don't mean to quibble, but it is Dhaka (not Dacca) and it is most definitely
nowhere near the middle east.

It is a quibble and you are of course right (although there IS a Dacca
file). But your observation is also entirely irrelevant to the OP question.
