Can we use XQuery-based tools to answer >this kind of question about RDF datasets? I'm not sure whether I understand the question. By "implied triples", do you mean the relationship between the times indicated by dates and times? XQuery can directly compare instances of datatypes to see if one is before the other - although that depends on work that has not yet been completed, the operators and functions work being done by a joint task force of XSL and XQuery, which will define the operators on datatypes. If "implied triples" means something else, it's probably time for me to learn about them ;-> I should mention that I am still exploring and learning, and the results of my work are not at all established.
