In the scientific literature there are many different ideas on the nature of time and its measurements but some assumptions seem quite debatable: i.e. the nature of time could depend on the type of physics dealing with it; that we could forget time, and so on. Of course we need to measure the duration of time both in everyday life and in science because we want to compare (instant by instant) sets of physical variables which typify an investigation. So that the comparison is possible, we need to use time as an alignment parameter. That could be a good definition.
