Note also the Thunderbolt has a wonderful feature -- packet
0x8E-A4 enables a test mode where you create your own
leap seconds whenever you want. It's a good way to test GPS
or NTP software without waiting until the next real leap second.

Hal,
Thanks, glad you have such good records. Maybe they are waiting until Jan.
28 to start transmitting it this time. I wonder what the magic formula is
as to when they start ?
Some had asked how I am able to view the data stream? I have a homemade
receiver that's set up where I can record the raw data. Since the previous
event, I wrote some software that will notify me when there is a pending
leap second and I need them to start transmitting it where I can verify my
software is working correctly!

Last time I checked (first of this week) subframe 4 of page 18 in the data
stream from the GPS satellites, they are not indicating there is a pending
leap second. Last time there was a leapsecond (couple years ago), I think
the GPS SV's were anouncing a pending leapsecond about 6 months in
advance.
Wonder when they will start sending it on GPS?
I just checked and my Z3801A isn't seeing it yet.
Last time, it started getting announced on July 28.
