What time of day does my subscription payment renew?

Subscription renewal payments are made at the same time of day that the subscription started, with a possible variance of one hour due to the whether your locale observes Daylight Savings Time. 

The date indicated for renewal in the account billing section of your dashboard is based on the UTC timezone which may be ahead or behind your local time zone. For example if you live in New York and you started membership at 9pm on November 1st, it will indicated on the products list that it renews on the 2nd of each month since that is actually 2am in UTC.
