earth's rotation
Different time zones are the result of Earth's rotation and the need to coordinate time across regions. The Earth is divided into 24 time zones, each roughly 15 degrees of longitude wide, with the prime meridian serving as the reference point (GMT). Time zones help to synchronize activities and schedules across the globe.
The longitude of a location determines its time zone because Earth is divided into 24 longitudinal zones, with each zone representing one hour of time difference from Coordinated Universal Time (UTC). Different time zones exist due to the Earth's rotation and the need to maintain consistent timekeeping across regions by adjusting for the varying position of the sun in the sky.
Time zones are based off of longitude
Ideally, you would have the same offset from Coordinated Universal Time (UTC) as the nearest multiple of 15° of longitude to you. To simplify: divide your longitude by 15°, then round the quotient to the nearest whole number. The result is the number of hours from UTC your location would be if the system were perfect, with east longitudes being ahead of UTC and west longitudes being behind UTC.
Only the Prime meridian determines time. The International Date Line determines days because it is a separator of Day 1 and Day 2. The equator, Tropic of Cancer, Tropic of Capricorn, Arctic Circle and Antarctic Circle determine different regions on Earth that have different climates.
Different time zones are the result of the Earth's rotation and the need to coordinate timekeeping across regions that experience sunlight at different times. The Earth is divided into 24 time zones, each roughly 15 degrees of longitude wide, with boundaries determined to synchronize activities across the globe.
The Prime Meridian (0 degrees longitude) and the International Date Line (180 degrees longitude) determine time zones across the globe. Time zones are typically one hour apart for every 15 degrees of longitude difference.
Time zones are primarily based on longitude rather than latitude. The Earth is divided into 24 longitudinal sections, each representing one hour of time difference. This allows for a standardized way to coordinate time across the globe.

It's the lines of longitude which are used to define time zones, not lattitude.
