Converts a relative binary timestamp to a tm structure. Format #include <utc.h> int utc_reltime(*timetm, *tns, *inacctm, *ins, *utc) struct tm *timetm; long *tns; struct tm *inacctm; long *ins; const utc_t *utc;
1 – Parameters
Input utc Relative binary timestamp. Output timetm Relative time component of the relative binary timestamp. The field tm_mday returns a value of -1 and the fields tm_year and tm_mon return values of zero. The field tm_yday contains the number of days of relative time. tns Nanoseconds since time component of the relative binary timestamp. inacctm Seconds of inaccuracy component of the relative binary timestamp. If the inaccuracy is finite, then tm_mday returns a value of -1 and tm_mon and tm_year return values of zero. The field tm_yday contains the inaccuracy in days. If the inaccuracy is infinite, all tm structure fields return values of -1. ins Nanoseconds of inaccuracy component of the relative binary timestamp.
2 – Description
The Relative Time routine converts a relative binary timestamp to a tm structure. Additional returns include nanoseconds since 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_mulftime routine.
