Rates that occured at the same time (UTC time) can be overlayed.
Rates that occured at different times (both 09:00 am local time) can,
AFAIK, not be overlayed. Some proposals have been done. I had to drop
development and to the best of my knowledge nobody picked it up.
Consider what happens to the connection between site A and site B:
If you would graph traffic for both sites in their own local time,
you'd get a peak at (say) 09:00 your local time _and_ a peak at
10:00 your local time (because it was _their_ 09:00 local time).
