SYNOPSIS

#include <iv.h>

extern struct timespec iv_now;

void iv_validate_now(void);

void iv_invalidate_now(void);

DESCRIPTION

iv_now is a global variable that reflects the current time-of-day. Applications written to the ivykis API generally require to know the current time-of-day in many places, and therefore effort is done to cache this quantity.

The contents of iv_now might be stale. Calling the function iv_validate_now ensures that the current contents of iv_now are up-to-date.

The function iv_invalidate_now is called to invalidate the currently cached time-of-day. This function should be called after any operation that takes a significant amount of wall clock time.
