For Bug 1827669 we've seen cookies being created which have a `createdAt` timestamp that is very far in the future. The exact cause and regression of this is currently unknown. We should add a check in the persistent cookie storage that either deletes or clamps these invalid cookies timestamps to the current date.

For Bug 1827669 we've seen cookies being created which have a `createdAt` timestamp that is very far in the future. The exact cause and potential regressor of this is currently unknown. We should add a check in the persistent cookie storage that either deletes or clamps these invalid cookies timestamps to the current date. Whenever we find cookies with a `createdAt` timestamp far in the future we can collect telemetry. This is to determine how many users are affected.
