Dear all, Now, for full disclosure, I am not completely unaffilliated, but I want to share this gem. Just published is a new book - "An Introduction to Modern Timekeeping and Time Transfer" by Parameswar Banerjee and Demetrios Matsakis. This book covers quite a bit of ground, and covers topics which include GNSS and Two-way Satellite Time Transfer, Timescales etc. I was asked to review a pair of chapters, and my feedback led me to review the content of the full book. My feedback was apparently well received and acted upon. I am proud and happy for the contribution, but more importantly I think this books is really good that it does not handwave on topics that other referernces handwave on, and I like that. Concrete examples on uncertainty for links etc. is shown. Therefore I recommend people to consider it. So, this week as we met at the ITSF conference in Antwerp, Demetrios very kindly gave me a copy of the book. We are however not the only time-nuts here, Ole Peter is also here. Also on display is the 5071B or "black 5071", so I've seen it in the flesh. Pendulum showed their CNT-104 counter, and I will take one for a test-run soon enough. Cheers, Magnus
