column ClockIdentity
The clockIdentity is an 8 octet array formed by 
mapping an IEEE EUI-48 assigned to the time-aware system 
to IEEE EUI-64 format (i.e., to an array of 8 octets).  
The EUI-48 shall be an Ethernet MAC address owned by the 
organization creating the instance of a clockIdentity  
under the terms of this subclause. The organization 
owning the MAC address shall ensure that the 
MAC address is used in generating only a single instance 
of a clockIdentity, for example by requiring that the 
MAC address be a MAC address embedded in the device 
identified by the clockIdentity. The mapping rules for 
constructing the EUI-64 from the EUI-48 shall be those 
specified by the IEEE [B2]. The 8 octets of the created 
IEEE EUI-64 shall be assigned in order to the 8 octet 
array clockIdentity with most significant octet of the 
IEEE EUI-64 assigned to the clockIdentity octet array 
member with index 0.(see 8.5.2.2).
