One of my Colleagues was asking me about Day Light saving time, and I immediately remembered Seth’s posts on the DST. To the people who do not know the history of DST, it is pretty interesting to get to know about the concept and its usage in the current era.The main purpose of Daylight Saving Time (called “Summer Time” in many places in the world) is to make better use of daylight. We change our clocks during the summer months to move an hour of daylight from the morning to the evening.During DST, clocks are turned forward an hour, effectively moving an hour of daylight from the morning to the evening.
