Converts a tm structure that expresses local time to a binary
    timestamp.

    Format

      #include <utc.h>

      int utc_mklocaltime(*utc, *timetm, tns, *inacctm, ins)

         utc_t *utc;
         const struct tm *timetm;
         long tns;
         const struct tm *inacctm;
         long ins;

1 - Parameters

    Input

 timetm

    A tm structure that expresses the local time. On input, tm_wday
    and tm_yday are ignored.

 tns

    Nanoseconds since time component.

 inacctm

    A tm structure that expresses days, hours, minutes, and seconds
    of inaccuracy. If tm_yday is negative, the inaccuracy is
    considered to be infinite. On input, tm_mday, tm_mon, tm_wday,
    tm_isdst, tm_gmtoff, and tm_zone are ignored.

 ins

    Nanoseconds of inaccuracy component.

    Output

 utc

    Resulting binary timestamp.

2 - Description

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

    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 inputs include nanoseconds since the last second of
    time and nanoseconds of inaccuracy.

3 - Returns

     0   Indicates that the routine executed successfully.
    -1   Indicates an invalid time argument or invalid results.

4 - Example

    See the sample program for the utc_cmpmidtime routine.
