Power management

DST means resetting of time in the summer. At the very beginning of the summer, the clock time is to be advanced one hour and at the end of the season it will be set as it was.
DST was first started in the UK on 21 May 1916. Then Russia, Australia and Canada adopted it. Now many developed and developing countries practice DST system to save daytime.
We should consider the option in our country also.
