Remarks

Most applications should just use the CorrectionOffset property.

The same data structure represents both request and reply packets. Request and reply differ in which properties are set and to what values.

The only real property is Bytes. All other properties read from and write to the underlying byte array with the exception of DestinationTimestamp, which is not part of the packet on network and it is instead set locally after receiving the packet.
