[tz] Philippine Standard Time

In the Philippines, there is a national law, Republic Act No. 10535 
which declares the official time here as "Philippine Standard Time". 
The act [1] even specifies use of PST as the abbreviation, although
the FAQ provided by PAGASA [2] uses the "acronym PhST to distinguish
it from the Pacific Standard Time (PST)."

(Interestingly, the act does nothing to define the actual value of
Philippine Standard Time; there is no UTC offset or other reference.
It simply declares what the time is called, and instructs government
agencies to coordinate with PAGASA for synchronization.  :)  There are
references to "Section 6 of Batas Pambansa Bilang 8" [3] (which
directs the adoption of the Metric System), but Section 6 merely
delegates the task of establishing the definition of "second" to
PAGASA.  I've been unable so far to find any specific implementing
regulation that establishes an official 8-hour offset from GMT.)

Not long ago, the TZ database clean-up of "invented" abbreviations
removed the PST abbreviation for Asia/Manila, leaving us with no

Based on the existence of national law declaring Philippine Standard
Time, and formally establishing the abbreviation/acronym, could we
please get "PST" (or, if you prefer, "PhST") re-included into the next
update of the TZDB?
