Certainly. Though it may be that you only have a single offset due to whatever business rules, and you never use HOURS_IN_MILLISECONDS, it's always either 6*HOURS_IN_MILLISECONDS or some other term. I didn't want to have to think of an actual domain case, but just show an example of when having a clear, named constant rather than a, yes, unchanging, but ultimately not intuitive and easy to get wrong value, is a better choice; I readily admit you can run that down further once you have a real domain. :P
