Title: Re: Explain the physical basis of standard time zones Post by: bio_man on Apr 2, 2017 The Earth's rotation makes the highest sun of the day (solar noon) pass westward over 15° of longitude per hour. In 24 hours the sun passes over 360° of longitude (15° per hour times 24 hours equals 360°). Thus there is one theoretical time zone per 15° of longitude.
