i'm confused to how this is different to waking up to the sunrise that is also (almost) at the same time every day?
I don't know where you live but even at my latitude it most definitely is not "at almost the same time every day."
If I woke up with the sunrise in winter I'd be waking up 2 hours later than in the summer (3, really, because of daylight saving time).
The time doesn't change by a lot every day, sure, but that's not relevant to things like transportation or work schedules.
