[mdlug] Upgrading from Ubuntu 12.04 to 14.04 makes hardware clock stay on UTC

[R Kannan]

Thanks to all who answered.

Bob, My Ubuntu version of /etc/default/rcS does not have the comment you 
have below.

I will try disabling NTP and see if that helps. Was NTP not on by 
default in Ubuntu 12.04 which I was using before?
