The decc$fix_time routine converts an OpenVMS binary system time (a 64-bit quadword containing the number of 100-nanosecond ticks since 00:00 November 17, 1858) to a UNIX binary time (a longword containing the number of seconds since 00:00 January 1, 1970). This routine is useful for converting binary times returned by OpenVMS system services and RMS services to the format used by some C RTL routines, such as ctime and localtime.
