NAME¶
taia_now - get current time
SYNTAX¶
#include <taia.h>
extern int
taia_now(struct taia*
t);
DESCRIPTION¶
taia_now puts the current time into
t. More precisely: tai_now puts into
t its best guess as to the TAI64NA label for the 1-attosecond interval
that contains the current time.
This implementation of taia_now assumes that the time_t returned from the time
function represents the number of TAI seconds since 1970-01-01 00:00:10 TAI.
This matches the convention used by the Olson tz library in ``right'' mode.
Beware that many clocks are not set accurately, and even the best scientific
clocks are nowhere near 1-attosecond accuracy; however, an inaccurate clock
may still produce reasonably accurate time differences.
