I'm late in the discussion. I rebooted my Thunderbolt this morning and it shows a date of 1998 in Thunderbolt Monitor -- and also shows the same incorrect date on my Thunderbolt's LCD display. I purchased the large LCD unit on eBay a few years ago but I no longer recall who supplied it. A photo can be seen in a link on my QRZ.com page at https://www.qrz.com/db/w9ac See the hyperlink "GPS-Locked Frequency Standard" in the introduction paragraph. So, at this time is there a viable solution that will make the LCD read the proper date? I am less concerned about the date showing accurately on the desktop Thunderbolt Monitor program. Many thanks!
