It should only be the failure of producing the wrong "display-date".
The internal time system use different gears for everything, so the
display-date is a side-product. Adjust with +1024 weeks and you should
be all set. Leap-second info work on internal gears.

Well quite an unpleasant surprise. So after the 30th do the TBolts stop
working or is it a case of just the wrong date? I know my Hp3801s been
working just fine and its old. Is the TBolt the same issue. Wrong date but
still locks thats all I care about actually.
With to respect of some sort of a hack I can see that being fairly
difficult.

I cannot imagine a work around since the problem stems from the GPS
service
only identifying the current date within a particular 1024 weeks epoch
unless the government changes the amount of data that is sent over the
GPS
system. Somebody has to use other method to determine the epoch and add
the
corresponding offset.
There is: There is a 13bit week number in message type 10. This gives
a 157 year span instead of the ~19 years of the 10bit week number.
This has been part of the GPS standard since IS-GPS-200D which was
released in 2004. As such I am a little bit surprised that the u-blox
receivers still don't support this message (the LEA-5 family was released
in 2007 IIRC). But you can use the UBX RXM-SFRBX messages to get the
raw GPS messages and decode them yourself.
