Just a convenient demarcation point. I remember reading somewhere that it was the calendar. However, in looking in _VAX/VMS Internals and Data Structures_ (ver 3 edition) ch 11.1.2 page 215: "The system time is defined by a quadword value measuring the number of 100-nanosecond intervals since 00:00 hours, November 17, 1858 (the time base for the Smithsonian Institution astronomical calendar)." Which, of course, is probably based on the above mentioned julian day. +-----------------------------------------------------------------------------+ | | Dave E Martin | DISCLAIMER: Been Cancelled | | /\ | "...between the streets of | $ opinion/mine/noUinTech | | / \ . /\ | Dallas, and the beaches of |----------------------------| | / \/ \/\/ \ | Miami ...
