IP Timestamp Option
Like the ICMP TIMESTAMP request, IP also has a timestamp
option (type 68) that measures the number of milliseconds since
midnight UT. This could also be used to determine down to a
millisecond resolution what the remote system's clock is set to.
Since the measurement is the same, the limitations are the same as
ICMP's TIMESTAMP request.
