.TH taia_now 3
.SH NAME
taia_now \- get current time
.SH SYNTAX
.B #include <libowfat/taia.h>
extern int \fBtaia_now\fP(struct taia* \fIt\fR);
.SH DESCRIPTION
taia_now puts the current time into \fIt\fR. More precisely: tai_now puts into
\fIt\fR 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.
