[-- Attachment #1 --] Your Y2K web page states: "Note also that the OS expects to read the current date and time from the CMOS clock of your computer. Not all of these devices correctly handle the year 2000. You are advised to test each platform individually to ensure that your hardware clock behaves correctly when going from 1999 to 2000, and that it correctly interprets the year 2000 as a leap year." I presume that this means that the Real Time Clock is directly accessed by FreeBSD, rather than via the BIOS. Many new PCs (even now) are BIOS compliant but not RTC compliant. It means we have to be extra careful about which PCs we run FreeBSD on. Can you confirm please ? Thanks.
