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.
JST is 15 hours ahead of CST (standard time).
Daylight Saving Time: CST observes DST; JST does not. The offset between them shifts by 1 hour twice a year — in spring and autumn — when CST changes its clocks.
