I found a government page with the same information, possibly the origin of it, on

There is more information on other issues, but the wording of the DST bit is
the same. On a personal note they are really trying to test the limit of timezone
handling software, choosing First Saturday and First Sunday of a month as a
parameter,  probably not realizing that these can be mutually exclusive, maby
meaning that if First Sunday is first day of month, it will not be counted (as in 2007).
Choosing fixed date of October as DST end date, when the start date is
parameterized to a weekend, is highly obscure too - but not difficult to handle.

Thanks for the heads-up.  I looked around and found these copies of
what appears to be essentially the same source:

(dated 2001-12-06) which says that the Cabinet adopted a scheme "to
advance the clocks by one hour on the night between the first Saturday
and Sunday of April and revert to the original position on 15th
October each year".  This agrees with your April 7 at 00:00, but
disagrees about the October transition, and makes it sound like it's
not on a trial basis.

Also, the "between the first Saturday and Sunday of April" phrase, if
taken literally, means that the transition takes place at 00:00 on the
first Sunday on or after April 2, not the more-usual April 1.  The
first year that this would make a difference is 2007.

For what it's worth, Shanks says that the last transition from DST in
what is now Pakistan also occurred at 00:00 on October 15.  The year
was 1945.
