Hi They may have some odd setting deep in the scpi to get the log over to this or that time frame. I’d have thought that UTC would be the obvious choice. It also could just be a bug. Bob On Dec 6, 2014, at 5:23 PM, Paul tic-...@bodosom.net wrote: I was curious about the six second

Hi Oh, ok. Any time you have a power “burp” the clock will start back at what ever it thinks was the time was last. That sounds simple. It’s not. If you want to save your eeprom or flash from burnout, you don’t write “it’s now ..” once a second. If you do, things die fairly quickly. I have

Hi Here’s what I’m suggesting: The local time is updated *after* the GPS Valid hits the log. Put another way, the time used for the log is *not* corrected to GPS time until after the valid message is logged. Bob On Dec 7, 2014, at 2:59 PM, Paul tic-...@bodosom.net wrote: On Sun, Dec 7,

I was curious about the six second difference between GPS valid on the two boxes. Is that likely just due to (message) processing overhead? ___ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to
