(Alpha and I64 only.) The Convert Internal Time to External Time
    (IEEE S-Floating-Point Value) routine converts a delta internal
    OpenVMS system time into an external IEEE S-floating time.

    Format

      LIB$CVTS_FROM_INTERNAL_TIME  operation ,resultant-time

                                   ,input-time

1 - Returns

    OpenVMS usage:cond_value
    type:         longword (unsigned)
    access:       write only
    mechanism:    by value

2 - Arguments

 operation

    OpenVMS usage:function_code
    type:         longword (unsigned)
    access:       read only
    mechanism:    by reference

    The conversion to be performed. The operation argument is the
    address of an unsigned longword specifying the operation. Valid
    values for operation are the following:

    Operation              Interpretation

    LIB$K_DELTA_WEEKS_F    Fractional weeks
    LIB$K_DELTA_DAYS_F     Fractional days
    LIB$K_DELTA_HOURS_F    Fractional hours
    LIB$K_DELTA_MINUTES_F  Fractional minutes
    LIB$K_DELTA_SECONDS_F  Fractional seconds

 resultant-time

    OpenVMS usage:floating_point
    type:         IEEE S_floating
    access:       write only
    mechanism:    by reference

    The external time that results from the conversion. The
    resultant-time argument is the address of an IEEE S-floating-
    point value containing the result.

 input-time

    OpenVMS usage:date_time
    type:         quadword (unsigned)
    access:       read only
    mechanism:    by reference

    Delta time to be converted. The input-time argument is the
    address of an unsigned quadword containing the time.
