Here are the English names of all time zones in use in 2014 (the numbers in parentheses are their offsets from Coordinated Universal Time (UTC), & the letters after them are the two-letter ISO-3166 codes for the countries that use each zone name):
* Those time zone names that are listed twice, first with an asterisk then with their Summer Time name have a part that observes Daylight Saving Time/ Summer Time and a part that stays on Standard Time all year.
I think that's all of them... for now.
The officially inhabited lands of the world currently use 41 different time offsets. Five of them are used during only part of each year, but at least 38 are in use at any given time. So if you ask for the exact time on Earth, you should get at least 38 different answers.
I refer to clock settings as time offsets because a time zone is often expressed as an offset from Coordinated Universal Time (UTC). For example, Mountain Standard Time in North America is UTC - 7 hours, or UTC-7.
Several time zones can have the same time offset, or a time zone can have several different names, depending on how you look at it.
Most of the time zones in North America, Europe and Africa are named after the part of the continent where they are. Those names are shared by multiple countries. Most of the time zones in South America and Asia are named after the countries where they are used. Altogether the 41 time offsets or zones have 167 different names, including 34 that are used only for Daylight Saving Time or Summer Time.
Here are the 41 offsets from earliest to latest and the names used within each offset (Daylight Saving Time or Summer Time zone names are in parentheses):

Time zone information is often hard to find, and sources often contradict each other, so any corrections are eagerly welcome, either directly here or to my message board. -HW
At any given time, the clocks around the world are set to at least 38 different times, and these time zones have about 165 different names, including about 130 different names just for Standard Time designations.
All time zones are set by Coordinated Universal Time (UTC).
In the US there are six time zones, they have names they are called in the US and also have Greenwich Mean Time (GMT) Zone names: * US Eastern Standard Time = GMT - 5 * US Central Standard Time = GMT - 6 * US Mountain Standard Time = GMT -7 * US Pacific Standard Time = GMT - 8 * US Alaska Standard Time = GMT - 9 * US Hawaii-Aleutian Standard Time = GMT -10 In Summer most states in the six US time zones observe Daylight Savings Time and then the name of the zone would be, for example, US Eastern Daylight Time Zone.
There are 24 time zones in the world, one for each hour of the day. These time zones are based on lines of longitude and help standardize timekeeping across the globe.
Because the Earth is tilted on its axis. Therefore, sunlight doesn't always hit in the same spot all the time, so time zones have to be out of proportion.

Yes, but they are generally colloquial names. I don't think the names are necessarily recognized internationally.
In the continental US, the four zones are Eastern, Central, Mountain and Pacific.
There are 41 different time zones with 167 different names.
All time zones are set by Coordinated Universal Time (UTC).
Fleming did not name any time zones, and his idea was adopted by all countries, so names were given later. Nunavut covers 3 time zones, Mountain, Central, and Eastern, so it can be either 5, 6, or 7 hours behind GMT.
All continents have time zones. It is just that the continents are so big that they have many time zones in them.
