I just thought of another example that might help understand it.
Hermione's use of the time-turner for classes.

We don't really see the effects of this spelled out clearly through the
book... just hints, she appears and disappears at odd moments, but even
that is very much in the background. It's mostly just the question of
how she could be in '2 places at once'.

 From Hermione's perspective, she takes one class, uses the time-turner,
then takes the other class.  But from the perspective of Time, the
linear time everyone else is experiencing, she was always in both
classes.  She didn't miss a class, then reset history and take it.  She
was always there.  While she was taking her 'first' class, her future
self was at the same moment sitting in the other class.

I wonder how this sort of time travel affects aging, you know?  If
Hermione existed through, say, just 3 extra hours each week, over what,
40 school weeks?  That's 120 hours, or 5 whole days.  That's not much
from a lifetime's experience, but did her body, her cells, etc, age 5
extra days in that year?  In other words, do her cells live twice when
she 'goes back', or do they live concurrently in the 2 different bodies
at the same time, thus adding no age?  Or another way to look at it...
when she 'goes back', does her current self go back, or does she de-age,
going backwards in time physically as well?

I think the implication of the time-clock in the DoM would imply the
latter, although you do apparently take along your knowledge of the
intervening time, which implies the former...

Whee!  My brain is starting to get angry with me for making it try to
comprehend all this lol...
