Attributes:

• delay_ns (int) –

  The delay between reading the source clock time and writing it to the destination clock

• frequency_offset_ppb (int) –

  The frequency offset of the clock from the source clock in parts per billion

• offset_ns (int) –

  The offset of the clock from the source clock in nanoseconds, i.e. time(src) - time(dst)

• servo_state (ValueType) –

  The state of the clock servo

delay_ns instance-attribute

delay_ns: int

The delay between reading the source clock time and writing it to the destination clock Although nonsensical, PTP4L reports this as negative in some cases

frequency_offset_ppb instance-attribute

frequency_offset_ppb: int

The frequency offset of the clock from the source clock in parts per billion

offset_ns instance-attribute

offset_ns: int

The offset of the clock from the source clock in nanoseconds, i.e. time(src) - time(dst)

servo_state instance-attribute

servo_state: ValueType

The state of the clock servo
