UTC Offset: UTC +6

Indian Chagos Time (IOT) operates at UTC+6 hours year-round without daylight saving adjustments. Also known simply as "Chagos Time," IOT is the official time zone of the British Indian Ocean Territory, covering the Chagos Archipelago, and provides a stable and consistent time reference for this isolated region in the Indian Ocean.

Importance and Global Use of IOT

IOT is essential for managing operations on the Chagos Archipelago, including the coordination of activities at military facilities and research stations located there. Its fixed offset supports reliable scheduling for transportation, supply deliveries, and local administration in an area with limited infrastructure and a remote location.

Internationally, Indian Chagos Time helps align communications, logistics, and travel arrangements with neighboring regions and partners, especially in South Asia and the wider Indian Ocean. The UTC+6 offset provides clear time coordination for any diplomatic, strategic, or scientific activities connected with the territory.
