Machine-readable rule source
Exact offsets and transition rows come from the IANA Time Zone Database as exposed by the deployed runtime. IANA publishes tzdb releases when governments change civil-time rules.

What Indian/Chagos is useful for
A timezone page should do more than define an offset. These notes connect the zone to city clocks, DST behavior, converters, and adjacent country planning pages.
Zone identity
Indian/Chagos is rendered as IOT at UTC+06:00 for British Indian Ocean Territory. The IANA zone ID is the stable key; the abbreviation is only the short display label.
DST behavior
Indian/Chagos has no scheduled offset transitions in the next 12 months. The displayed UTC+06:00 is stable year-round, which makes long-horizon scheduling, billing, and report-window math straightforward.
City coverage
1 indexable city sits in this zone after locale and crawl-safety filters, with Chagos among the examples shown.
Conversion handoff
IOT has no pre-built converter pair, so a custom comparison runs through the general timezone converter instead.
Adjacent planning context
The most useful next steps from this timezone page are city clocks. Those links keep the zone page connected to real user tasks rather than stopping at an offset definition.
Single-abbreviation behavior
Indian/Chagos resolves to a single abbreviation, GMT+6, in the next 12 months. That makes the abbreviation usable as a short display label, but the IANA zone is still the canonical key for storage and conversion math.
Offset stability
Indian/Chagos spends about 365 days at UTC+06:00 across the forward 12-month window, which makes it stable across the entire window. The remaining time is split across the other offsets listed in the year-of-DST card.
Peer zones at the same offset
Other IANA zones currently aligned at UTC+06:00 include Asia/Dhaka, Asia/Thimphu, Asia/Urumqi, Asia/Bishkek, and Asia/Omsk. Same-offset peers can drift apart later in the year if their DST rules differ, so a peer match today is not a permanent equivalence.
Country roster
Indian/Chagos is used as the primary clock anchor for British Indian Ocean Territory. The roster is derived from country-zone mappings, so it reflects which jurisdictions adopt this IANA zone rather than which countries happen to share its current offset.
Timezone abbreviations can be ambiguous. The IANA zone name is the canonical key used for clocks, city pages, and conversion math.

Year-round offset behavior
Indian/Chagos across the next 12 months
