Going back in time to get home

I left Seoul this afternoon at 2:00 and arrived in San Francisco 12 noon the same day. I wonder if I can continue this to get younger?

I am presently very jetlagged but I plan to slog it through and get on San Francisco time by as soon as I can. I find it much easier to adjust to Asian time when I go from the West coast to there and find it more difficult to adjust to Westcoast time coming from Asia.
