What GMT and PHT Actually Are
GMT — Greenwich Mean Time
The UK and Ireland in winter, plus Iceland, Portugal and much of West Africa. Standing at UTC as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, October 25, 2026, to GMT. Often used loosely as a synonym for UTC. They differ by less than a second, so for scheduling they are interchangeable.
Britain ran an experiment from 1968 to 1971 on permanent UTC+1, abandoning GMT entirely. It was scrapped after complaints about dark winter mornings in Scotland.
PHT — Philippine Time
Manila, Quezon City, Cebu, Davao. Standing at UTC+8:00 as written, and the region does not change its clocks, so that offset holds all year. Also written PST for Philippine Standard Time, which collides with US Pacific Standard Time.
The Philippines briefly used daylight saving in 1990 during an energy crisis, and has otherwise kept a single fixed offset since independence.
What This Means in Practice
This gap is not fixed
GMT changes its clocks and PHT does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, October 25, 2026 unless someone resets it.
