Understanding the +9h Gap: Colombia vs GST

Colombia runs on Colombia Standard Time (COT) at UTC-05:00. GST runs on Gulf Standard Time (GST) at UTC+04:00. That puts Colombia 9 hours ahead of GST — a difference of +9h at the current offsets.

In practice, when it is 9:00 AM in Colombia it is 6:00 PM in GST. Midnight in Colombia is 9:00 AM in GST. Neither zone observes daylight saving time, so the offset between them stays constant all year.

Why people convert Colombia to GST time

  • Scheduling a call from Colombia to GST: a 10:00 AM start in Colombia lands at 7:00 PM in GST, so you can confirm the slot without doing the arithmetic yourself.
  • Handling a +9h gap: Colombia and GST 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 GST is 6:00 PM in Colombia.
  • Watching a live event or market open: Colombia viewers need 6:00 PM in GST to catch a 9:00 AM start there, and 3:00 PM if the event is anchored to Colombia.
  • Always state the zone abbreviation, not just the hour. "3:00 PM COT" is unambiguous; "3 PM" across a +9h gap is not.
  • With a +9h gap there is no shared 9-to-5 window, so alternate the early start: one week Colombia takes the early slot, the next week GST does.
