when is the beginning of one day on mylot?

I can't be certain, but I believe the day for the purpose of cutting off earnings is midnight, possibly eastern U.S. time. Again, that's a guess on my part.

As for the top discussions, that fluctuates throughout the day anyway, so I don't think it really matters. They rotate them to give more exposure, I believe.

I am curious about that as well. I get the impression that the day will begin some time in the next hour because it says that the earning were updated 23 hours ago. I think the earnings are a day behind because the numbers were a little lower than my actual posts were, but I guess I will see in about an hour. I should have a better ideas by tomorrow I hope.

I don't think anyone really knows this for sure, but I think the new day starts at midnight. The reason for this belief is that I have done very little work before midnight a few times, but worked a lot after midnight, and I wouldn't earn much at all, but the next day I would get my earnings for the time I put in after midnight.
