I've changed the timing submissions to include an option for adding milliseconds to your time. This is not necessary at all, and has been implemented mostly because of the challenge levels and how easily times can tie. You don't need to worry about putting down milliseconds if you don't want to, it's mostly only there for tie breakers on challenge levels. If two runs tie within the same millisecond range (I haven't determined the range at the time of posting this as it is unnecessary at the moment), I will manually look at both times to make sure the times are as accurate as possible. If I see two times on the leaderboard that tie and one or both does not have milliseconds on the submission, I will manually edit it, so feel free to not worry about milliseconds if you do not want to.
