My difficulty is perhaps simpler. The question refers to what Peterinadequately
observes and asks what Jane observes. Both sound to me like descriptions of
a proper time interval, and I don't know in which reference frame to place
myself to answer the question. I often find this difficulty in basic SR
problems. Am I missing something, or is it that ambiguous questions are
common in this area?

Peter and Jane are each wearing a wristwatch with a second hand that takes
one minute to make one complete revolution and Peter is moving at a speed
of 0.9c with respect to Jane. When Peter observes the second hand on his
watch to have made one complete revolution, how many revolutions will Jane
observe the second hand of her watch to have made?

What time is observed to elapse in a frame moving at 0.9c with respect to
a frame where one minute elapses?
According to Ronald Mallett UConn, at least, this is an indeterminate
question,
in that one of the observers might be circling the other slowly,
and traveling backwards in time.
