SGT to GMT Time Converter
SGT means Singapore Standard Time (UTC+8); GMT means Greenwich Mean Time (UTC+0). These named offsets do not change with the season. The city planner below follows local clock changes instead.
GMT means UTC+0 year-round. London uses GMT in winter. When the UK observes summer time the abbreviation becomes BST (British Summer Time, UTC+1). GMT and UTC share the same offset (UTC+0) but are technically distinct standards. The city planner uses Europe/London.
- 9:00 AM SGT = 1:00 AM GMT
- 12:00 PM SGT = 4:00 AM GMT
- 5:00 PM SGT = 9:00 AM GMT
