Please note that it is the Saturday _night_ before Yom Kippur -- i.e. in reality (and this is what is stated in the final wording of the law), the last _Sunday_ before Yom Kippur at 02:00 a.m. Moreover, please note that Iran uses the Persian calendar for both the starting and end dates of Daylight Saving Time so that calendar too would have to be part of the software. ___________________________________________________________________________ Ephraim Silverberg, CSE System Group, Phone number: 972-2-6585521 Hebrew University, Jerusalem, Israel.
