Perhaps your computer's understanding of what 'Canada/Newfoundland'
means is not up to date.

I believe that you should be 2.5 hours behind UTC at this point.

Do a 'date -u' and see if that is accurately reflecting UTC.  That's all
that NTP will do.  If 'date -u' is correct and 'date' is incorrect, then
your computer's timezone definitions are out-of-date.

Update them with whatever method is correct for your OS.

   'zdump -v Canada/Newfoundland | grep 2007'
on your computer may also be illuminating, but has nothing to do with
