68U: Will Changing Starting day of Monthly Cycle Mess Things Up?

[MarkRH]

I've been saving my Traffic Data for the past few months to a USB stick. If I change the monthly cycle start time from the 1st to the 15th to match my ISPs billing cycle, will it:

1. Just automatically shift things around with the existing data?
2. Wipe everything and have to start over?
3. Leave everything as is, but break the current cycle on May 15th?

Just wondered what would happen.
Thanks,

Well, I changed the date to 15 which changed nothing with the existing information. See what happens when the 15th rolls around.
