|  |     A friend of mine goes by the name of Vincenzo Stanley Fojut ( his
    mother's Italian, his  father is Polish), he says that if he ever
    has a son he'll call him Tempus.

|  |     Any calendar experts know why 17-Nov-1858 was chosen as VMS's
    zero date?

|  |     According to my reference (VAX-11 Run-Time Library Language Support
    Reference Manual, Sect. 5.3.1) the DATE$ function:
    
    "...returns the date corresponding to day number n, where n is the
    day of the year (1 to 365 or 366) plus the number of years since
    00-JAN-1970 * 1000."
    How did you arrive at 17-NOV-1858?

|  |     It's the date of the first astronomical photograph.

|  |     When I switch on Monday mornings I feel like it's my date of birth.

   Yes, I'm afraid you are.  :-)  
   I don't have a copy of the manual you mention, but I believe the DATE$
   function is based on the BASIC DATE$ function, which indeed uses
   00-JAN-1970 as it's base date.  (If I remember correctly, RSTS/E uses
   that as it's base date, too.)
   
   Most other date oriented functions in VMS use 17-NOV-1858 as the base
   date.  I quote from the VAX/VMS System Services Reference Manual (VMS V4.2), 
   VAX/VMS System Services Reference Manual, p. 9-2:
        VAX/VMS maintains the current date and time in 64-bit format.  The
        time value is a binary number in 100-nanosecond units offset from
        the system base date and time, which is 00:00 o'clock, 17-Nov-1858
        (the Smithsonian base date and time for the astronomical calendar).
