tai_now - get current time, with 1-second precision

#include <tai.h>

void tai_now(&t);

struct tai t;

tai_now puts the current time into t.

More precisely: tai_now puts into t its best guess as to the TAI64 label for the 1-second interval that contains the current time.

This implementation of tai_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.
