Philippine Standard Time

From Wikipedia, the free encyclopedia

Philippine Standard Time (Filipino: Pamantayang Oras ng Pilipinas, abbreviated PST) or unofficially, Philippine Time (abbreviated PHT), is the name used in the Philippines to describe its location among the world's time zones. Modern Philippine Standard Time was instituted through Batas Pambansa Blg. 8, the law defining the metric system, which was approved on December 2, 1978 and implemented on January 1, 1983.

Geographically, the Philippines lies within 116°40′ and 126°34′ east of the Prime Meridian, and as such is physically located within the UTC+8 time zone. Philippine Standard Time is maintained by the Philippine Atmospheric, Geophysical and Astronomical Services Administration, or PAGASA.

In the 1990s, due to frequent power outages, daylight saving time was instituted. As the Philippine power supply and transmission systems recovered, daylight saving time was ended, and is presently not in use.
