DECdts, utc_reltime

|
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;
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.
The Relative Time routine converts a relative binary timestamp to
a tm structure. Additional returns include nanoseconds since time
and nanoseconds of inaccuracy.
0 Indicates that the routine executed successfully.
-1 Indicates an invalid time argument or invalid results.
See the sample program for the utc_mulftime routine.
