There's hidden "eng" menu with many options. No documentation is
available for this menu, so I had to find things out by trial and error.
In the "timing" menu there's offset_time option. This shows -100 at
default and one step is 100ns --> 10 uS. Setting this to zero the PPS
moves to sync with Thunderbolt!
But the setting is not permament, it's lost with reboot. Unable to find
out how to "save" this permamently. And hard to understood why this is
even set to -10 uS!
There's also commands to read and write the eeprom contents (it's good
idea to read it and copy-paste the contenst to the safe place). However
the offset_time is not stored to eeprom, even with JP4 in place. Too sad!
