time_t approx_time | ( | void | ) |
Return a cached estimate of the current time from when update_approx_time() was last called. This is a hack to avoid calling time(NULL) on critical paths: please do not even think of calling it anywhere else.

void update_approx_time | ( | time_t | now | ) |
Update the cached estimate of the current time. This function SHOULD be called once per second, and MUST be called before the first call to get_approx_time.
