How do I compute the date of the 1st Sunday of April and the last Sunday in October given the year? I'm working on a project in which a real-time clock has to correct itself for DST automatically. Any ideas? Thanks alot Dana Rodakis
"this means your product won't go international." Not sure what you mean by this - how you calculate it doesn't affect whether you also have the means to specify different dates to suit different countries and/or timezones? I'm not even sure that there is a deterministic formula for when BST applies?
Unless this 10-years DST table I was talking about can be programmed to XDATA, then you can certainly make your product none country dependent.
