Proposed Text on Clocks

I propose the following to be insterted into the introduction:

1.6 Time Assumptions

CDL has been designed to support intra and inter business activity. In such an environment, it is acceptable for different parties to be synchronizsed on second boundaries and not by finer grained boundaries such as milli, micro, or nano seconds. 
Thus there is an assumption that each party is responsible for its own synchronization to UTC and that no clock synchronisation protocol is required. Applying CDL to a different environment where finer granularity and synchronisation is required, e.g. real-time embedded systems, is possible, but will required additional support not defined here.
