* @brief Universal Time Object Implementation.
*
* This is an encapsulation of the time. It provides the following
* operations on basic time.
* - Construction of a UTO from piece parts, and extraction of the
* piece parts from a UTO. The piece parts are the readonly
* attributes :
* time
* inaccuracy
* time displacement factor
* structure with all the above.
* - Comparison of time.
* - Conversion from relative to absolute time, and conversion to
* an interval (TIO).
