I use the AID-HUI message to get the time of the next leapsecond. I use 
the utcWNF and utcDN to get the day number of the next leap second. 
Since it always happens at the end of the UTC day, this gives you the 
time. utcLS and utcLSF give you the the before/after offsets. Yes, it 
doesn't change often, but it doesn't need to.

There are very few messages that have any leap second info, and I had hoped that the aiding message AID-HUI would do something at the leap second.  But, the message doesn't seem to update more than once a day and there's no direct way to tell when the leap second will happen from the AID-HUI message that I can see.  So, does anyone have a good grasp on how to get the pending leap second info from a Ublox receiver?  I'm missing something that's probably intuitively obvious to everyone else.
