Zulu time and Greenwich Mean Time are the exact same thing, as is typical of the military, it coined its own term. Since Greenwich is the site of the "zero meridian," they called GMT "Zero Time" or simply "Z- Time." In the phonetic alphabet that the flyers of the time used to make themselves understood on their radios, "Z" became "Zebra." When the alphabet was changed, the call sign became "Zulu." Clarification: They are not *exactly* the same thing. Zulu time does not shift with daylight savings time. It is a constant time that the military uses and in fact coined a term for. They did not just call GMT by a new name, they created a new standard time.
Zulu Time - or Greenwich Mean Time is just an agreed standard that all other time zones relate to. So rather than a submarine commander having to worry about what time it is in Pearl Harbor and what time in Washington DC - Zulu time as the world standard is used to avoid confusion.
Mountain Daylight Saving Time is 6 hours behind Zulu Time. Mountain Standard Time is 7 hours behind Zulu Time.
The time zones each have a letter designation. Except there is no "I" or "O". The GMT zone has the letter "Z". For which the standard communications word for is ZULU. (As in Alpha, Bravo, etc.) Armond Noble
To convert military time to Zulu time, you need to account for the time zone difference between the military time zone and Coordinated Universal Time (Zulu time). Simply subtract the military time zone offset from the military time to get Zulu time. For example, if the military time is in GMT+1, subtract 1 hour from the military time to get Zulu time.

0300Z is the same as 0300GMT. Greenwich Mean Time (GMT) is commonly referred to as Zulu Time (Z) in the aviation and military sectors.
Zulu time is also knows as Universal Coordinated Time. It is usually expressed in terms of a 24 hour clock. Zulu time is the primary time standard used by the military.
Zulu time is named after the phonetic letter Z used in the NATO phonetic alphabet. It is derived from Coordinated Universal Time (UTC) and is used in aviation and military operations to avoid confusion with different time zones.

Most world military forces do not have any effect for time zones, as they use what is often referred to as Zulu time (which is the same as what is now UTC, but historically was GMT) outside of their local area. Therefore, if an operation is happening outside of a local area (under the same time zone), the tradition is to convert it to Z (Zulu) time, and activate it at the appropriate time. Feel free to run a "GOOGLE" for terms that you do not understand above.
The military work on Zulu time, which is GMT (Greenwich mean time) or UTC (Universal Time) - which are basically the same but differ in name. This allows any unit, to coordinate any operation to a standard time, without having to worry about time differences. The "military" time is coordinated to GMT but the local time is dependant on your location.
PST stands for Pacific Standard Time and is UTC-8 during non-Daylight Saving Time and UTC-7 during Daylight Saving Time. Zulu time is another term for Coordinated Universal Time (UTC), which is the primary time standard by which the world regulates clocks and time. Zulu time does not change with Daylight Saving Time shifts.
Zulu time is based on a 24 hour system, there is no am or pm. 6am is the same as 0600h 11:59 am is the same as 1159h 1pm is the same as 1300h 5pm is the same as 1700h 9pm is the same as 2100h 11:59pm is the same as 2359h
Iowa is in the US Central Standard Time Zone which is the same as GMT -6, UTC -6, and Military Zulu time zone S (Sierra).
