You could change your location. You move 15 degrees about the earth as
you add or subtract 1 to or from your TZ. And space and time are equivalent,
no?

Play with this script:

	set -v
	TZ=5 date
	TZ=-19 date
	TZ=-43 date
	TZ=-163 date

What it shows me:

	TZ=5 date
	Fri Jul 17 20:46:58  1992
	TZ=-19 date
	Sat Jul 18 20:46:58  1992
	TZ=-43 date
	Sun Jul 19 20:46:58  1992
	TZ=-163 date
	Fri Jul 24 20:46:58  1992
