How Time Zone Conversion Works
Time zone conversion works by comparing the UTC offset of one location to another. Every city or region is measured relative to Coordinated Universal Time (UTC), which acts as the global reference point for civil time.
SGT is 8 hours ahead of GMT (standard time).
Daylight Saving Time: GMT observes DST; SGT does not. The offset between them shifts by 1 hour twice a year — in spring and autumn — when GMT changes its clocks.
