Y2K Compliance

Yes, Xerces-J and Xerces-C are Year 2000 compliant. They do not currently use any dates at all (at least until the XML Schema date datatypes are fully supported). However, you may still have Y2K problems if the underlying OS or Java implementation has problems with dates past year 2000 (e.g. OS calls which accept or return year numbers).

Most (UNIX) systems store dates internally as signed 32-bit integers which contain the number of seconds since 1st January 1970, so the magic boundary to worry about is the year 2038 and not 2000. But modern operating systems shouldn't cause any trouble at all.
