Symptoms

As reported in various publications around the world, Pakistan has announced the start of DST for 2009 on April 15th at midnight. This information is subject to change as it has not been officially confirmed by a Pakistani government source. This optional hotfix updates the start of Daylight Savings Time (DST) for Pakistan in 2009 according to those reports. The clock will move one hour forward at midnight between April 14 and April 15, and then move one hour back at midnight between October 31 and November 1 in 2009. There was no DST for Pakistan in 2009 prior to this announcement.

More specifically, this article sets DST for Pakistan as follows:
  • DST starts at 23:59:59 on April 14, 2009
  • DST ends at 23:59:59 on October 31, 2009
