Why people convert PST to Singapore time

- Handling a +16h gap: PST and Singapore have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Singapore is 1:00 AM in PST.
- Keeping family and friends in sync: knowing that 8:00 PM in PST is 12:00 PM in Singapore makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM PST" is unambiguous; "3 PM" across a +16h gap is not.
- With a +16h gap there is no shared 9-to-5 window, so alternate the early start: one week PST takes the early slot, the next week Singapore does.
