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.
