Does the Oyster peak time charge depend on entry time, exit time, or
if any part of the journey is between 0700-1900 M-F?

For example: am I charged peak rate if I touch in at 0645 and touch
out at 0715? and similarly touching in at 1845 and touching out at
1915?

The entry time is what counts. So, in your examples, the answers would
be No and Yes.
