Re: [time-nuts] Rollover : Thunderbolt
My ancient T'bolt (purchased well-used several months ago) also went from 1023 to 1024. A quick look at IQ phase data I was recording (referred to a free-running PRS-10) shows no discernible glitch at the moment of rollover. This old T'bolt has been living in 1999 for as long as I've had it. So tonight it went from Aug 21, 1999 to Aug 22, 1999. I'll be interested in seeing what that date does over the next several months. I also have a CNS Clock II, which went smoothly to week 2048, and it shows the correct UTC date. I confess that I forgot to see what week # it showed before the big event, but suspect it was 2047 (not 1023). Shame on me!

Re: [time-nuts] Rollover : Thunderbolt
Well! I must have misunderstood something. At 23:59:42 on 06 April, LadyHeather informed me that my Thunderbolt changed from week number 1023 to 1024. Drama! Suspense! Excitement! I had expected a reset from 1023 to 0. But that isn't what happened. Maybe in another 20 years ... 73, ...

Re: [time-nuts] Rollover: Thunderbolt
Hi One device on that list is the NetRS. If you have one and are not on the latest firmware, the upgrade is free and fairly easy to do. TBolt’s show up as “non-compliant / no fix / end of life long past”. There are a number of other devices from various outfits that also fall into this “no solution” category. On some of the other gear the cost to do the upgrade could well be into the “yikes” range. For most outfits there is a per device upgrade fee. You actually are coming up to date on the entire firmware, not just patching the week number issue.
