Strange. I have three of these that I have tracked pretty closely for several 
years. To my knowledge, I’ve never experienced any circumstance in which they 
were off by one or more seconds. 

Regarding the holdover behavior, I have not tested that.  But if you believe 
that the current behavior is incorrect, why don’t you reach out directly to Leo 
to discuss?  In my experience he is pretty responsive and thoughtful regarding 
issues with the device.
