13	  The IEEE 1588 standard defines a method to precisely
14	  synchronize distributed clocks over Ethernet networks. The
15	  standard defines a Precision Time Protocol (PTP), which can
16	  be used to achieve synchronization within a few dozen
17	  microseconds. In addition, with the help of special hardware
18	  time stamping units, it can be possible to achieve
19	  synchronization to within a few hundred nanoseconds.

21	  This driver adds support for PTP clocks as character
22	  devices. If you want to use a PTP clock, then you should
23	  also enable at least one clock driver as well.
