Philippine Standard Time

Philippine Standard Time
Time zone
The Clock tower of Manila City Hall is the icon for synchronizing the time in the whole Philippine archipelago, before an atomic clock was introduced in the country in 2012. The purposes of these Philippine "towering timepieces" are to tell the time and to serve as landmarks.

Philippine Standard Time (PST ^{[1] [2]} or PhST; ^{[3] [4]} Filipino : Pamantayang Oras ng Pilipinas), also known as Philippine Time (PHT),^{[ citation needed ]} is the official name for the time zone used in the Philippines. The country only uses a single time zone, at an offset of UTC+08:00, but has used daylight saving time for brief periods in the 20th century until July 28, 1990.

Geographic details

Countries that use UTC+08:00 are in yellow.

Geographically, the Philippines lies within 116°53′^{[ clarification needed ]} and 126°34′^{[ clarification needed ]} east of the Prime Meridian, ^[5] and is physically located within the UTC+08:00 time zone. Philippine Standard Time is maintained by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA). The Philippines shares the same time zone with China, Taiwan, Hong Kong, Macau, Malaysia, Singapore, Western Australia, Brunei, Irkutsk (Russia), Central Indonesia, and most of Mongolia.

History

Erroneous International Date Line from the 1888 Meyers Konversations-Lexikon , running between the Spanish Philippine Islands and British Hong Kong. The Philippine Islands along with the rest of New Spain are shown on the eastern side of the IDL, even though they were moved to the western side in 1845. It also placed Bonin Islands and Fiji to the east those are actually to the west of the line.

For 323 years, 9 months, and 4 days which lasted from Saturday, March 16, 1521 (Julian Calendar), until December 30, 1844 (Gregorian Calendar), the Philippines had the same date as Mexico, because it had been a Spanish colony supplied and controlled via Mexico until Mexico's independence on September 27, 1821. On August 16, 1844, the Spanish Governor-General Narciso Claveria decreed that Tuesday, December 31, 1844, should be removed from the Philippine calendar. Monday, December 30, 1844, was immediately followed by Wednesday, January 1, 1845, which added 1 day or 24 hours to the local time. This meant that International Date Line moved from going west of the Philippines to go on the east side of the country. ^{[6] [7]} At the time, the local mean time was used to set clocks, meaning that every place used its own local time based on its longitude because the time was measured by locally observing the Sun.

Philippine Standard Time was instituted through Batas Pambansa Blg. 8 (that defined the metric system), approved on December 2, 1978, and implemented on January 1, 1983. The Philippines is one of the few countries to officially and almost exclusively use the 12-hour clock in non-military situations.^{[ citation needed ][ dubious ]}

In September 2011, the Department of Science and Technology proposed to synchronize time nationwide, which was an effort to discourage tardiness and non-standard time displayed on television and radio stations. PAGASA installed a rubidium atomic clock, a GPS receiver, a time interval counter, a distribution amplifier, and a computer to help calculate the time difference with every satellite within its antenna's field of view. ^{[8] [9]}

In a bid to discourage the Filipino culture of tardiness, on May 15, 2013, President Benigno Aquino III signed Republic Act No. 10535 setting the Philippine Standard Time, ^[10] requiring all government offices and media networks to synchronize their timepieces with PAGASA's rubidium atomic clock. ^{[11] [12]}

Notes

1. The change also applied to Caroline Islands, Guam, Marianas Islands, Marshall Islands and Palau for being part of the Captaincy General of the Philippines during that time.
2. During World War II, the Philippines became under control of Imperial Japan following the "Fall of Manila" on January 2, 1942, caused by the invasion of the Imperial Japanese Army. However, Japan was defeated by the United States Navy at the Battle of Leyte Gulf and then liberate Visayas on October 26, 1944. After few days, the clocks set back to Philippine Standard Time.

1. The term UTC (Coordinated Universal Time) begin in use just after the introduction of Unix Time on January 1, 1970. In those days before 1970, the GMT (Greenwich Mean Time) was the term being used.
