I've gone to the Marina del Rey Supercharger twice now at just after midnight when the rate drops to .11/kw. I've started the charge a few minutes after midnight, car shows the rate should be .11/kw but I've been twice charged the peak rate of .50/kw. I finally figured out how to call Tesla regarding the the charging situation and provided evidence of the .11/kw rate on my car's screen. They said it's a widely known issue where the clocks in the supercharger are behind about 5-10 minutes. I asked for a refund of the difference after they acknowledged the issue is on their end and they said no refunds will be given. They admitted this is a widespread issue and from what I've seen on reddit, it goes back at least 3 months, if not a lot longer. They're essentially robbing everyone that is charging right when the rate changes and I wouldn't be surprised if people don't even realize they're being charged the wrong rate.
Needless to say, I'm very pissed about this. In the meantime, DON'T start charging until at least 10 minutes after the rates are supposed to change.
