It already is. You can time travel for at most a few days when you cross the dateline. If we could possibly make a larger dateline and compress it like our intestines, crossing that could possibly time travel more. There is one glitch however, you have no control over where and when you travel to. NOTE: This is only a theory. The larger dateline has not been tested.
The international dateline. Situated at 180 degrees east (or west) through the Pacific ocean with a few kinks to avoid going through countires.
If you pass west over the International Date Line, you subtract a day from your calendar. This means that when you cross the line, you effectively move into the previous day. For example, if it’s Monday when you cross, it will become Sunday. This adjustment is necessary to keep the calendar aligned with the Earth's rotation and local time zones.
