IANA zones · the technical identifiers
The zone that resolve to CST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about CST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Has Colombia ever used daylight saving time?
- Once. From May 3, 1992 to February 7, 1993, Colombia moved its clocks forward to UTC-04:00 to save electricity during a drought-driven power crisis. It has stayed on UTC-05:00 ever since.
- Is Colombia Standard Time the same as U.S. Eastern Standard Time, and do they ever drift apart?
- They share UTC-05:00, so Colombia and the U.S. East Coast read the same hour from November to March. When the States spring forward in March, Bogotá stays put and sits an hour behind New York until November.
- How does Colombia’s time compare with Venezuela, Peru and Ecuador?
- Peru and mainland Ecuador use UTC-05:00 all year, the same as Colombia. Venezuela uses UTC-04:00 all year, one hour ahead of Bogotá. None of them observe daylight saving time.
