I'm using an Extreme Engineering XPort 3200 grandmaster clock in my system. It expects to get its base timing signal from a 1PPS signal driven by an ICD-GPS-153 compliant receiver, and publish it via ptp. I had to work out an upstream replacement for the stock ts2phc, and as I fix my last bugs on that I have a question about its behavior. When the board comes up cold, the clock just runs from zero in both the phc clock and system clock on the board. The current UTC time is a long way from zero. Will ts2phc try to steer it to current time, or will it recognize that there is a big gap, and just reset the phc clock? Likewise, will phc2sys steer the system clock or jump it?
Thanks! -- David
