WR PTP Core: Setting time in GrandMaster mode overwrites alignment to external source
WR PTP Core running in GrandMaster mode is locked to external 1-PPS and 10 MHz. When user wants to set manualy time and date (without fractional part of a second), the nanoseconds counter in PPS_GEN is overwritten. That makes the Master node no longer aligned to 1-PPS and 10MHz coming from external time source.
