Hi, all I find that even if I have mon clock skew warning, under most cases, my cluster still can work properly as expected. I go through the code in mon but do not find any related issue without time_check() to update whether clock skew periodically. can any one tell what is the design purpose of the clock skew between mon and when it will really matter the cluster? Thanks a lots!
