ICT → GSTGap: -3h5h 9-5 overlap

ICT to GST currently uses Indochina Time in Asia/Ho_Chi_Minh and Gulf Time in Asia/Dubai as the live reference pair. Right now the gap is -3h, and the sections below break that into meeting-time shortcuts, workday overlap, DST changes, and city coverage on both sides.

Last updated Apr 22, 2026. Offset math, DST behavior, and city coverage on both sides are refreshed from the live timezone dataset during the page revalidation window.

Reverse: GST → ICT

Ambiguity note

GST is ambiguous in this dataset, so the live converter uses Asia/Dubai as the busiest reference zone while the city list below shows the wider label family.

Pair context

ICT and GST currently connect Ho Chi Minh City and Dubai with a live gap of -3h. Representative coverage on the ICT side is anchored by Ho Chi Minh City, Hanoi, Bangkok, and Haiphong, while the GST side is anchored by Dubai, Abu Dhabi, Sharjah, and Al Ain City.

Using a simple 9:00 AM to 5:00 PM workday on both sides, the pair shares about 5 hours of business overlap - roughly ICT 12:00 PM previous day to 5:00 PM previous day, which is GST 9:00 AM previous day to 2:00 PM previous day. There is still a usable shared block in the morning or afternoon, so teams can usually meet without pushing too far outside standard hours.

The live gap is -3h right now, based on Asia/Ho_Chi_Minh at +07:00 and Asia/Dubai at +04:00. Neither reference zone shows an offset change in the next year, so the gap should stay stable.

Market coverage on both sides

On the ICT side, the current dataset is anchored by cities such as Ho Chi Minh City, Vietnam; Hanoi, Vietnam; Bangkok, Thailand; Haiphong, Vietnam; Phnom Penh, Cambodia; Cần Thơ, Vietnam. That makes this page useful for real-world coordination patterns rather than only abstract offset math.

On the GST side, the live reference set includes Dubai, United Arab Emirates; Abu Dhabi, United Arab Emirates; Sharjah, United Arab Emirates; Al Ain City, United Arab Emirates; Muscat, Oman; Ajman, United Arab Emirates. In practice, that means the conversion is tied to recognizable business, travel, and support hubs rather than a single anonymous timezone label.

Country usage on the two sides currently includes Vietnam, Thailand, and Cambodia for ICT and United Arab Emirates, Oman, and South Georgia and the South Sandwich Islands for GST. That country coverage helps explain why some pairs feel like outsourcing, logistics, gaming, finance, or travel-heavy conversions while others are more niche.

Operational notes

ICT to GST meeting times is easiest to read as a working-day range rather than a single spot conversion. In the current snapshot, 9:00 AM lands at 6:00 AM, while 9:00 PM lands at 6:00 PM, which makes the practical handoff window much easier to scan.
