+  //
+  // = DESCRIPTION
+  //    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).
+public:
+  // = Initialization and termination methods.
