It can be altered,  but only by 50ns.   You can invert the phase of the osc sense (feature not available on Thunderbolt-E or Thunderbolts built before March 1998).  Use the '^' command in Lady Heather.

----------------------------------------
The PPS output is synchronous with the 10MHz signal and the delay from the preceding zero crossing of the 10Mhz signal to the leading PPS edge cannot be altered.
