The current model Thunderbolt E #60333-50<tel:60333-50>, v1.04 firmware has a last valid date on the 22nd December 2029<x-apple-data-detectors://1>.
It is probably a good idea to specify what firmware you have in these discussions as different versions will have different properties, and some of the used Thunderbolts are quite old.

It can compensate for any number of rollovers. In fact you can use it to adjust the receiver time by any number of seconds (including fractional seconds). The default behavior is to trigger after 10 seconds of consecutive time messages where the time is before year 2016. The 10 second filter is to avoid false triggers from corrupted packets. This means that for the first 10 seconds after starting Heather on a Tbolt, the date will be wrong. When rollover compensation is in effect, the date is shown in yellow and a "ro" flag appears next to it. It would nice if somebody could come up with a patched firmware... You can get a false rollover detection if you start monitoring a receiver before it has acquired the almanac since most receivers output time based upon the GPS epoch if they don't have an almanac. ---------------- The current version of Mark's Lady Heather program has code to detect this and fix it so you're good to go for the next 19.6 years. ------------------------------ Message: 2 Date: Fri, 28 Jul 2017 01:27:07 +0000 From: Mark Sims <hol...@hotmail.com<mailto:hol...@hotmail.com>> To: "time-nuts@febo.com<mailto:time-nuts@febo.com>" <time-nuts@febo.com<mailto:time-nuts@febo.com>> Subject: [time-nuts] Symmetricom X72 and Lady Heather results Message-ID: <sn1pr11mb102437f0ff83a8dadb9baf99ce...@sn1pr11mb1024.namprd11.prod.outlook.com<mailto:sn1pr11mb102437f0ff83a8dadb9baf99ce...@sn1pr11mb1024.namprd11.prod.outlook.com>> Content-Type: text/plain; charset="iso-8859-1" I'm in the process of adding support to Lady Heather for the Symmetricom X72 (and SA22) rubidium oscillators. I have a most of the functionality working. The X72 has a "health" message that dumps a couple dozen values. The values are labeled with some rather cryptic names that give some hint about what they are, but no where in their (miserable) documentation do they elaborate on what the values mean. Does anybody have any info on them. The X72 is user interface is a very frustrating an infuriating thing to work with. The device has several glaring omissions in what it does... like no way to read back any settings that you have made and no way to save most of them in EEPROM and no command to restore the unit to its factory default state. Attached is a plot showing most of the non-static health values... it looks like most of them are highly correlated with temperature. Without heavily average-filtering the display, the values look a lot like noise. -------------- next part -------------- A non-text attachment was scrubbed...
