Once again on 15th April 12am Pakistan Standard Time is advanced by hour making the GMT+6 Standard time for the country. This was done for having more benefit from the day light. Last year Government had saved about 500 Megawatts by day light saving. So from next year for day light saving clocks will be advanced from 1st April to 1st Octuber.
Daylight saving is not a very old concept for Pakistan. Pakistan have observed day light saving only twice before, one the last year and other once before few years ago. But few years ago accoding to government they didn’t had any benifit from day light saving so they had discontinued it. But again continued from the last year as its being proved to be benificial this year.
