Description

   The Local Time routine converts a binary timestamp to a tm
   structure that expresses local time.

   OpenVMS systems do not have a default time zone rule. You
   select a time zone by defining sys$timezone_rule during the
   sys$manager:net$configure.com procedure, or by explicitly
   defining sys$timezone_rule.

   Additional returns include nanoseconds since time and nanoseconds
   of inaccuracy.
