Turn a Indochina Time reading into Coordinated Universal Time. The panels show both clocks live, and the roller lets you line up any ICT time against its UTC equivalent.

THE CLOCKS ABOVE ALWAYS SHOW THE LIVE CURRENT TIME. THE ROLLER BELOW IS A LOOKUP TOOL — ROTATING IT NEVER CHANGES THEM.
ICT is 7 hours ahead of UTC
ET is 4 hours behind UTC
Thailand is 11 hours ahead of United States (Eastern)

Indochina Time is the local clock in Thailand. Converting it to UTC removes the local offset so the time can be shared with anyone in the world without ambiguity — which is exactly why UTC is used for servers, aviation and international scheduling.
Indochina Time is shared by Thailand, Vietnam, Cambodia and Laos.
Subtract the current offset shown in the offset panel from the local ICT time. If the result goes below 00:00, UTC is still on the previous date. Use the roller to read the pairing directly instead of doing the arithmetic.
ICT has no daylight saving changes, so the offset to UTC is stable all year. It is still calculated live from the Asia/Bangkok IANA database rather than hard-coded.
Early-morning or late-night local times frequently sit on a different UTC date. The converter labels every selection as SAME DAY, NEXT DAY or PREVIOUS DAY so a deadline written in UTC is never off by 24 hours.
Thailand does not observe daylight saving time. ICT is fixed at UTC +07:00.
