Clock time versus solar time
San Francisco's clock is unusually well matched to the sun: local noon falls within 10 minutes of the moment the sun is actually overhead. Most cities sit further out, because time zones follow borders rather than longitude.
During summer time that gap widens to 1 hour 10 minutes ahead of the sun, which is the whole point of the exercise — shifting daylight into the evening.
