  First, I briefly review the different conceptions of time held by three rival
interpretations of quantum theory: the collapse of the wave-packet, the
pilot-wave interpretation, and the Everett interpretation (Section 2).
  Then I turn to a much less controversial task: to expound the recent
understanding of the time-energy uncertainty principle, and indeed of
uncertainty principles in general, that has been established by such authors as
Busch, Hilgevoord and Uffink.
  Although this may at first seem a narrow topic, I point out connections to
other conceptual topics about time in quantum theory: for example, the question
under what circumstances there is a time operator (Section 4.3).
