See the centuryCutoff global property im the Rev docs. The core of the problem reflects a limitation of the date routines in most OSes (the original Mac OS, for example, natively handles date ranges from 1904 to 2042). The solution is to use Julian dates. This was the topic of a long thread on the MetaCard list last fall. Perhaps the most complete algorithm was listed in this message: <http://www.mail-archive.com/[email protected]/msg04054.html> You may also want to search for "Julian" in the MetaCard List archives to get some more detailed background info on the issues involved. Would be nicer to have DateToJulian and JulianToDate functions built into the engine.... -- Richard Gaskin Fourth World Media Corporation Custom Software and Web Development for All Major Platforms Developer of WebMerge 2.0: Publish any Database on Any Site ___________________________________________________________ [EMAIL PROTECTED] http://www.FourthWorld.com Tel: 323-225-3717 AIM: FourthWorldInc _______________________________________________ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
