Good Evening:

Now that we are on the topic of the RTC, is it possible to change the 
update frequency.  I understand that a crystal controlled clock drifts a 
few seconds per month.  I also heard (unofficial) that routers, 
computers, tablets, phones, etc. do a net update daily.  Shouldn't a 
monthly update be enough, except for those few cases that more often is 
necessary?  Wouldn't this reduce the traffic on the net by, say, a lot?  
Wouldn't that be a good thing?  I have never seen a prompt to vary the 
update frequency.
