Converts a timespec structure to a binary timestamp. Format #include <utc.h> int utc_mkbintime(*utc, *timesp, *inaccsp) utc_t *utc; const timespec_t *timesp; const timespec_t *inaccsp; long tdf;
1 – Parameters
Input timesp A timespec structure that expresses time since 1970-01- 01:00:00:00.0+0:00I0. inaccsp A timespec structure that expresses inaccuracy. If tv_sec is set to a value of -1, the inaccuracy is considered to be infinite. tdf TDF component of the binary timestamp. Output utc Resulting binary timestamp.
2 – Description
The Make Binary Time routine converts a timespec structure time to a binary timestamp. The TDF input is used as the TDF of the binary timestamp.
3 – Returns
0 Indicates that the routine executed successfully. -1 Indicates an invalid time argument or invalid results.
4 – Example
The following example obtains the current time from time(), converts it to a binary timestamp with an inaccuracy of 5.2 seconds, and specifies GMT. timespec_t ttime, tinacc; utc_t utc; /* * Obtain the current time (without the inaccuracy)... */ ttime.tv_sec = time((time_t *)0); ttime.tv_nsec = 0; /* * Specify the inaccuracy... */ tinacc.tv_sec = 5; tinacc.tv_nsec = 200000000; /* * Convert to a binary timestamp... */ utc_mkbintime(&utc, /* Out: Binary timestamp */ &ttime, /* In: Current time in timespec */ &tinacc, /* In: 5.2 seconds in timespec */ 0); /* In: TDF of GMT */
