Yup, The protocol for the communications from the GPS satellites to the
GPS receiver only send the year infrequently.  The sats mostly send the
GPS week, which is modulo 1024.

It just takes a while before the GPS figures out what the current year
is an then tells gpsd about it.  So be patient and the time will 
eventually correct itself.

Could be either because the desktop already knew the current year, or
you caught the GPS stream after it figured out the current year.
