Clock time and sun time in Ciudad Juarez
A time zone is an agreement, and the sun does not follow it exactly. Ciudad Juárez, the largest city in this zone, lies at about 106.5° west. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 7 hours 6 minutes behind UTC. The clock is set to UTC−7. The sun is therefore highest in the sky at about 12:06 pm by the clock on standard time, and at about 1:06 pm while the clocks are moved (UTC−6). That is a close match: clock and sun agree to within a quarter of an hour. Other places in the zone, to the east or west of Ciudad Juárez, see the sun peak a little earlier or later. Through the year the figure also drifts by up to a quarter of an hour either way.
How long the day is
Ciudad Juárez is about 31.7° north of the equator. On the longest day of the year, around 21 June, the sun is up for about 14 hours 13 minutes. On the shortest, around 21 December, for about 10 hours 4 minutes. That swing of about 4 hours 9 minutes between summer and winter is the reason clocks are moved here: the extra summer daylight is shifted from the early morning to the evening.
