Quoting Daniel Gimpelevich (daniel at gimpelevich.san-francisco.ca.us):

The latter arrangement would be hideously confusing for people, so no.
We're changing uniformly to (official) 1-9pm hours, going forward.  (To
reiterate yet again, people may still arrive whenever they want from 1pm
on, and may stay after 9pm if they're quiet-and-we-really-mean-it-quiet.)
