 NAME

   utc_abstime - Computes the absolute value of a relative binary
                 timestamp

 SYNOPSIS

   #include <dce/utc.h>

   int utc_abstime( utc_t* result,
                    utc_t *utc );

 PARAMETERS

   Input

   utc
       Relative binary timestamp. Use NULL if you want this routine to
       use the current time for this parameter.

   Output

   result
       Absolute value of the input relative binary timestamp.

 DESCRIPTION

   The utc_abstime() routine computes the absolute value of a relative
   binary timestamp. The input timestamp represents a relative (delta)
   time.

 RETURN VALUES

    0    Indicates that the routine executed successfully.

   -1    Indicates an invalid time parameter or invalid results.

 EXAMPLES

   The following example scales a relative time, computes its absolute
   value, and prints the result.

        utc_t       relutc, scaledutc;
        char        timstr[UTC_MAX_STR_LEN];

     /* Make sure relative timestamp represents a positive interval... */

        utc_abstime(&relutc,            /* Out: Abs-value of rel time  */
                    &relutc);           /* In:  Relative time to scale */

        /*  Scale it by a factor of 17...  */

        utc_multime(&scaledutc,         /* Out: Scaled relative time   */
                    &relutc,            /* In:  Relative time to scale */
                    17L);               /* In:  Scale factor           */

        utc_ascreltime(timstr,          /* Out: ASCII relative time    */
                       UTC_MAX_STR_LEN, /* In:  Length of input string */
                       &scaledutc);     /* In:  Relative time to       */
                                        /*      convert                */

        printf("%s\n",timstr);

        /* Scale it by a factor of 17.65...  */

        utc_mulftime(&scaledutc,        /* Out: Scaled relative time   */
                     &relutc,           /* In:  Relative time to scale */
                     17.65);            /* In:  Scale factor           */

        utc_ascreltime(timstr,          /* Out: ASCII relative time    */
                       UTC_MAX_STR_LEN, /* In:  Length of input string */
                       &scaledutc);     /* In:  Relative time to       */
                                        /*      convert                */

        printf("%s\n",timstr);
