About PHT (Philippine Time)
Philippine Time (PHT) is fixed at UTC+08:00 all year. The Philippines has not observed daylight saving time since 1978, apart from a brief trial in 1990. PHT shares its offset with China Standard Time, Hong Kong Time, Singapore Time, Malaysian Time and Australian Western Standard Time, which makes Manila a convenient bridge for scheduling across East and Southeast Asia. As one of the world's largest centres for business process outsourcing, Manila keeps overlapping hours with both Australia and, on early shifts, the United States, and its contact-centre schedules are usually planned around Manila local time.
About GMT (Greenwich Mean Time)
Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude). GMT serves as the reference point from which all other time zones are calculated. The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.
