How long does thinset take to cure with granite tile

My tile guy laid 12 x 12 granite floor tile on Monday for my new basement bathroom. Due to the concrete floor being uneven he used a mortar and thinset mix (fortified versabond white and mortar/stucco mix) to help level the tiles. He was scheduled to come today, Wednesday, to grout but the thinset was not dry so I re-scheduled for Thursday.

Wondering how long I should wait for the thinset to cure before grouting? Will it do any harm to grout before the thinset is completely cured?

The granite is visibly darker and I am guessing it is due to moisture and will return to it's lighter color...is this a correct assupmtion?

Just some additional info...I live in Metro DC area
