Nothing.  It's normal.

NMEA feeds from GPS receivers have rather low priority for timing data 
and can easily err by this sort of amount.

Actually, you may be able to fudge the NMEA (note spelling) time to 
compensate for the systematic part of the error, but there is no 
guarantee that there won't be a large random component.
