Why people convert SGT to Colombia time

Scheduling a call from SGT to Colombia: a 10:00 AM start in SGT lands at 9:00 PM in Colombia the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -13h gap: SGT and Colombia 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 Colombia is 8:00 PM in SGT.
Keeping family and friends in sync: knowing that 8:00 PM in SGT is 7:00 AM in Colombia makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM SGT" is unambiguous; "3 PM" across a -13h gap is not.
With a -13h gap there is no shared 9-to-5 window, so alternate the early start: one week SGT takes the early slot, the next week Colombia does.
