Chile Standard Time (CLT)

Introduction

Chile Standard Time (CLT) is the time zone used in most of mainland Chile during the winter months. It is four hours behind Coordinated Universal Time (UTC-4). This time zone is unique to Chile and is used to standardize time across the country during the non-daylight saving period.

Time Zone History

The history of Chile Standard Time dates back to the early 20th century. On March 1, 1894, the first official time signal was operated in Valparaiso. Over the years, the time zone has undergone several changes. In 1910, Chile adopted GMT-5 as its official time. By 1919, the time was set to 4 hours, 42 minutes, and 46.3 seconds behind Greenwich. The current standard time (UTC-4) was established in the mid-20th century and has been adjusted periodically to accommodate daylight saving time.
