> I'd be interested to how how you are extracting this data.

For the Thunderbolt GPSDO, search for the words leap second
in the ThunderBoltBook2003.PDF document. Packet 0x8F-AC.

I think all GPS timing receivers have a similar feature. Some
receivers wait until the beginning of the month before they
turn on the bit. So you'll see it after June 1, 2012.

For the Motorola Oncore receivers you can get additional
information; the various LSF fields which tell you the day
and week numbers and the future leap second count.

For extra fun, most of the Oncore's also have a command
to return the raw bits from the satellites in which case you
can bit bang all the subframe data yourself.
