[LEAPSECS] TAI adjustment ??

[Tom Van Baak]

Hal,

That same adjustment to TAI nicely shows up in this recent paper:

"Developing a pulsar-based timescale"
http://arxiv.org/abs/1011.5285
http://arxiv.org/pdf/1011.5285v1 (PDF)

It will be interesting to see how this all plays out over the coming
years and decades. Think PDO (Pulsar Disciplined Oscillator),
or perhaps more practical, PDGPSDO.
