Maybe the baker got up and started baking every day at 4am, year-round. Sunrise changes throughout the year. Sunrise in December and July are not the same thing. To set the clock, they’d need a reference for the solar time to clock time for the current day. I ran into this in Rome when I visited last year. A church there has a giant solar clock where the sun shows up on a line on the floor at noon (or so I was told). At noon, nothing happened. After thinking for a second, I realized I would need to find solar noon, and went to Wolfram Alpha to find that solar noon, in Rome, on that day, was 1:19pm. The other option would be for the town to arbitrarily set the clock to solar noon one day, and just go with it, letting the drift be the drift. But the time would not be the same as it was before the reset. It could be an hour or more off.
