I think they mean what time you'll release the update. For example, January 10th, at around 1:00 PM PST. I think they want to gauge when to check in for the update?
I'm working on scaling for the sprites, I want to have them displayed in a better quality, and then I test the builds before uploading them, but it should be out a bit after the noon in Europe, so in the morning in Americas and early evening in Asia.
