- 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
