utc_gmtime(3dts)

Synopsis

#include <dce/utc.h>

int utc_gmtime(
struct tm *timetm,
long *tns,
struct tm *inacctm,
long *ins,
utc_t *utc);

Parameters

Input

utc
Binary timestamp to be converted to tm structure components. Use NULL if you want this routine to use the current time for this parameter.

Output

timetm
Time component of the binary timestamp.

tns
Nanoseconds since the Time component of the binary timestamp.

inacctm
Seconds of the inaccuracy component of the binary timestamp. If the inaccuracy is finite, then tm_mday returns a value of 1 and tm_mon and tm_year return values of 0 (zero). The field tm_yday contains the inaccuracy in days. If the inaccuracy is unspecified, all tm structure fields return values of 1.

ins
Nanoseconds of the inaccuracy component of the binary timestamp. If the inaccuracy is unspecified, ins returns a value of 1.

Description
The utc_gmtime( ) routine converts a binary timestamp to a tm structure that expresses GMT (or the equivalent UTC). Additional returns include nanoseconds since Time, and nanoseconds of inaccuracy.

Return Values
~0 Indicates that the routine executed successfully.

1 Indicates an invalid time argument or invalid results.

Examples
See the sample program in the utc_cmpintervaltime(3dts) reference page.
