I don't suppose there is any way to change this? I just forgot again (OK, my problem but my not work so good anymore) and plugged it in around 10:00 AM with a scheduled time to start of 11:00 PM, and it started charging (and it doesn't seem to tell me when it starts charging, just when it's done, which, of course, is too late). I can't believe that I'm the only one that runs into this problem. If they would let me set the "grace period", then I could fix it. I don't really need any grace period at all, as I always set it to charge after 11:00 PM when the rates are the lowest, and I never plug it in later than that.
