Why people convert Indonesia to PHT time

Scheduling a call from Indonesia to PHT: a 10:00 AM start in Indonesia lands at 11:00 AM in PHT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Indonesia and PHT are inside the 9-to-5 working day between 9:00 AM and 4:00 PM WIB time (10:00 AM–5:00 PM PHT). That is roughly 7 hours of usable overlap.
Booking travel or deliveries: tracking PHT local time against Indonesia keeps pickup windows and arrival estimates honest across the +1h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM WIB" is unambiguous; "3 PM" across a +1h gap is not.
Block 9:00 AM–4:00 PM WIB as the recurring meeting window if you work primarily from Indonesia and need PHT colleagues present.

About WIB (Western Indonesia Time)

Western Indonesia Time (WIB, Waktu Indonesia Barat) is one of Indonesia's three time zones, fixed at UTC+07:00 all year. It covers Java, Sumatra, West Kalimantan and the provinces around them — home to Jakarta, the country's capital and largest city, plus Surabaya and Bandung. Indonesia does not observe daylight saving time, so WIB never shifts. WIB shares its UTC+07:00 offset with Indochina Time (ICT) and Christmas Island Time, but is a distinct zone covering the western half of the Indonesian archipelago. The country's other zones are WITA (UTC+08:00) in the centre and WIT (UTC+09:00) in the east.

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.
