Time Zone names, codes and abbreviations for Standard Time1 and Daylight Saving Time (DST)2 around the world.
1 Standard time is the local time in a country or region when Daylight Saving Time (DST) is not in use.
Standard time is sometimes referred to as winter time or normal time, while DST may also be called summer time, especially in the UK.
2 Daylight Saving Time (DST) is the practice of setting the clocks forward one hour from standard time during the summer months, and back again in the fall, in order to make better use of natural daylight.
UTC – Universal Coordinated Time is the common time standard across the world.
