Clock time and sun time in Turks and Caicos Islands

A time zone is an agreement, and the sun does not follow it exactly. Providenciales, the largest city in this zone, lies at about 72.2° west. Each degree of longitude is worth four minutes, so by the sun alone its time would be about 4 hours 49 minutes behind UTC. The clock is set to UTC−5. The sun is therefore highest in the sky at about 11:49 am by the clock on standard time, and at about 12:49 pm while the clocks are moved (UTC−4). 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 Providenciales, 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

Providenciales is about 21.8° north of the equator. On the longest day of the year, around 21 June, the sun is up for about 13 hours 28 minutes. On the shortest, around 21 December, for about 10 hours 48 minutes. That swing of about 2 hours 40 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.
