.TH taia_now 3 |
|
.SH NAME |
|
taia_now \- get current time |
|
.SH SYNTAX |
|
.B #include <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. |
