FW: source file correction for tzdata (egypt end of daylight savings)

[Olson, Arthur David (NIH/NCI) [E]]

I’m forwarding this message from John D. Martin III, who is not on the time zone mailing list. Those of you who are on the time zone mailing list, please direct replies appropriately.

John's message indicates a change at the midnight between Friday, August 21 and Saturday, August 22 while the current "Africa" file indicates a change at the midnight between Thursday, August 20 and Friday, August 21. Is there anyone with boots on the ground in Egypt who can tell us what actually happened last week?

I am sending some info about the end of daylight savings time for Egypt in 2009. The line for 2009 for Egypt/Cairo in 'africa' within the tzdata source should read :

Rule    Egypt   2009    only    -       Aug     21           23:00s    0    -
Rule    Egypt   2010    max    -      Sep      lastThu    23:00s    0    -

The beginning of Ramadan has been used to determine the switch to standard time. In 2009 the switch occurred on 21 August at midnight or the third Thursday of the month. This will likely revert in 2010 to the standard time in the last week in September.

Thanks. J
