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 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.
