[TriLUG] Best NTP client?

[Brian via TriLUG]

Hi Folks,

I've got a laptop that I routinely boot with either Windows 10 or Debian 
8.9 (Jessie).  Trouble is I can't get them both to agree on what the 
system clock is (UTC or local), so every time I switch OSes, the clock 
goes wonky.

Windows handles NTP sort of automagically, but that doesn't seem to be 
the case on my Jessie system.  So, I'm trying to figure out the best NTP 
client to use.

I poked around with chronyd, but it doesn't seem to be geared toward 
systems with inconsistent internet connections (e.g. it seems to require 
user intervention to get going again if servers can't be reached during 
boot).

What do folks recommend?  I really just want something I don't need to 
think about----it should always run, and just update the clock whenever 
an internet connection is available.

Thanks,
-Brian
