Final answer:
A Time Zone Wheel may not be exactly accurate due to the inconsistent boundary lines of time zones and the presence of the International Date Line.
Step-by-step explanation:
There are multiple reasons why a Time Zone Wheel may not be exactly accurate in real life. One reason is that time zones do not necessarily follow state, regional, or local boundaries, resulting in varied boundary lines that can make time zones wider or narrower than 15 degrees. For example, in the United States, time zone boundaries zigzag to follow state lines or keep cities within a single time zone. Another reason is the presence of the International Date Line, where time changes by a full day as you cross it, causing discrepancies in time zone accuracy.
