Data Plus (DP) offers a comprehensive set of 67 Client and similar number of Server functions designed to extend the built-in DateTime functions, all within a single solution. Over half of these functions are entirely new and are not available in OutSystems' standard built-in functions. The remaining functions include enhanced versions of existing ones, unified with consistent terminology for easier usability and recall. All DP function names begin with DP_*, ensuring they are easy to identify. This structure helps users quickly navigate through the library, find relevant functions, and streamline their work. Future updates will include additional functions while maintaining the current naming convention. The current version includes a total of 67 DT functions.
