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.
CLT is 4 hours behind GMT (standard time).
Daylight Saving Time: GMT observes DST; CLT does not. The offset between them shifts by 1 hour twice a year — in spring and autumn — when GMT changes its clocks.

Continental Chile observes DST (CLT UTC−4 ↔ CLST UTC−3). Magallanes and Aysén regions remain on UTC−3 year-round (America/Punta_Arenas). Easter Island uses a separate offset (UTC−6 standard / UTC−5 summer). Chile's DST transitions occur at midnight local time (not 02:00 as in North America/Europe). When CLST is active, mainland Chile and Argentina are on the same clock time (UTC−3).
