Change subject: [Feature] Allow normalization of WbTime objects
......................................................................
[Feature] Allow normalization of WbTime objects
* Makes a new WbTime object that omits any parameters that
are not represented by the precision
* Handles precisions lower than "year"
Bug: T123888
