NAME
       iv_now, iv_validate_now, iv_invalidate_now - ivykis time handling

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 represents a monotonic timer.

       The  contents  of iv_now might be stale.	 Calling the function iv_vali‐
       date_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.   This function should be called after any operation that
       takes a significant amount of wall clock time.
