Yes it includes working with those values, but in general stands for 'Internal Time Management' system(if i remember correctly, someone please correct me if i'm wrong). The general system includes those messages for easy metrical-timing solutions, but also incorporates all the objects that can use them and be synced-to or used with 'transport'(metro, translate, etc. and any signal-rate objects that take timing arguments like phasor~, rate~, etc.) Clearest description i've found is actually in the API: https://cycling74.com/sdk/MaxSDK-6.0.4/html/chapter_itm.html (but you don't really need to know all that, you could just learn from the included help docs like these: https://docs.cycling74.com/max7/vignettes/timing_events_topic) (☝️HAHA! "How can I possibly compose the next 'Williams Mix' without a timeline?" 😆😆 I'm guessing Gregory or Les wrote that one 😁)

Ah that was very helpful, thanks! 🤣
