You have probably incorrectly set the timezone on your Linux machine (or 
there is a daylight saving time discrepancy between reality and your 
OS's timezone definitions). NTP always works in UTC so getting correct 
local time depends on your computer knowing the UTC offset.

You don't necessarily need to know the UTC offset, just select the 
correct timezone based on your country/city and in most cases it will be 
set automatically. If you select a fixed UTC offset instead of the 
country/city setting, beware that it will not do automatic daylight 
saving time corrections, they will have to be set manually by changing 
the timezone when the switch takes place.

Depending on your Linux distribution the proper way to set the timezone 
varies, in Red Hat / Fedora a program called timeconfig will let you 
select the timezone.
