The further south you go (closer to the equator) the wider the time zone is. The further north (closer to the north pole) the closer together (in miles/kilometers) the boundaries get.
If we lived on a featureless ball the zones would be straight lines from pole to pole 15o apart. Since it is convenient to follow country, state or provincial borders the distance between zones at the same latitude varies both in miles/kiometers and degrees If you lived on the equator it would be roughly 1000 miles wide. the time zone would narrow (in miles or km) the further north you traveled until you reached the north pole, where it would be zero. You would actually be in ALL time zones simultaneously.
As an approximation, the circumference of the earth is 24,000 miles. There are 24 hours in a day (but there are actually more than 24 time zones as there are some 1/2 hour divisions). Ignoring this, there are thus approximately 24,000/24 hours = 1000 nautical miles per hour of time zone.
Guyana has one time zone, which is the Guyana Time Zone (GMT-4).
One
Illinios has only 1 timezone namely Central Daylight Time (CDT)
Central Time is one hour behind Eastern time. So if it's 5:00 Central time then it's 6:00 Eastern time.

Uganda has one time zone.
one The whole country uses UTC + 5½ hours.
Guyana has one time zone, which is the Guyana Time Zone (GMT-4).
Puerto Rico is entirely within one time zone, the Atlantic Time Zone.
The flight time from Hong Kong to Osaka is 3.5 hours. The flight distance is 1,549 miles (2,493 kilometers or 1,346 nautical miles). Osaka's time zone is one hour ahead of Hong Kong's time zone.
There is only one time zone in Tajikistan
One time zone. North Korea, South Korea, and Japan share a time zone.
