Every change is independent. Each state makes its own rules (well, has the freedom to decide what it wants, although there is apparently some federal oversight).
The only thing the state has control over is if it observes daylight savings time. Changing to a different time zone requires the Dept. of Transportation to approve of the change.
This is one of the things that makes this so complicated... most of the bills are “asking” the state government to petition the federal government to make a change. And it isn’t guaranteed that the DOT will approve the switch.
Even more complicated... the state can only control whether or not to observe DST. It can’t control the start/stop of DST, so if California wants to always be at UTC-7 (the current PDT), it couldn’t just decide to always be in PDT. It would need to petition the DOT to be moved to MST and then to not observe DST.
People are sick of changing their clocks by an hour twice a year as "daylight saving time" starts and ends. So there are many proposals to settle on permanent summer time or permanent winter time.
