As we are using time.owl here you are free to assert times using what granularity and time.owl properties fit, for instance only minutes. time.owl does not provide any precision notion (you could add a cusbtom one), but neither does it say much about time equivalense for instances. (interval have lots of time relations) So I believe there would be no conflicts, although in general it would make more sense to talk about intervals between different activities, etc.
