.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.
