It helps to make the daylight duration longer in summer by setting the clock 1 hour forward in the spring (start of DST period) and setting them 1 hour backward in autumn when the DST period is over.Introduction | Methods and Qualifiers | Data Layers | Sources | Services | Team | Special Thanks | Site Credits | Legal IntroductionĬlimate Central’s Surging Seas: Risk Zone map shows areas vulnerable to near-term floodingįrom different combinations of sea level rise, storm surge, tides, and tsunamis, Daylight Saving Time (DST)ĭaylight Saving Time (DST) is widely used in Europe and North America, and also in some parts of Africa, Australia, South America. A time offset is the amount of time added to or subtracted from UTC. Large Printable Colorful and with Time Zone Name revels offset. It replaced the Greenwich Mean Time (GMT) in the late 1960s, even though GMT remains today as a regional time zone at UTC+00:00. The official time standard that regulates the world’s time and clocks are called Coordinated Universal Time (UTC). Time zones measured according to the Greenwich Mean Time used as the starting meridian, which measured in hours before and after GMT. There are 24 different time zones, separated by one-hour intervals with each 15 degrees longitude. When someone is traveling by plane between two time zones, he or she will adjust his/her clock to the one used in the new zone. Within each time zone, people need to set their clock for the same time. The reason for this is that we divide the Earth into different time zones. When it is noon in Dhaka, it is midnight in New York. As a result, The World Time Zone Map is always different in various places on the planet. ![]()
