There are some cases where you not only care about the exact time (unix timestamps are fine for this) but also the timezone in which it was specified. I work on an app where users specify "people in california should see this at 3pm PDT" and get confused when they reload the page and it has been switched to "6pm EDT".
As an aside, moment-timezone it a godsend for dealing with timezone discrepancies. I would pay money for it.
