MNT: Added checks for a 'time' field
MNT: Added checks for a 'time' field

- First checks for 'time' at the event level
- Then checks for 'time' at the event['data'] level
- Finally grabs the seq_no from event if neither of the first two
  options are available

MNT: More robust try/except block for finding time in data
