You should be able to tokenize a precise day or hour of your (future) time and sell it. Maybe a blocktime-lock prevents the owner from redeeming it until the appropriate time. If you sell it high and buy it low, your time becomes a money printer.
If a bunch of people speculate on your time and you earn royalties on each trade before redemption, well then you really might become filthy rich haha
