The military time zones are a standardized, uniform set of time zones for expressing time across different regions of the world, named after the NATO phonetic alphabet. The Zulu time zone (Z) is equivalent to Coordinated Universal Time (UTC) and is often referred to as the military time zone.
Military time zones are lettered and given word designations from the NATO phonetic alphabet. For example, in US Eastern Standard Time (UTC−5), which is designated time zone R, 2:00 a.m. is written "0200R" and spoken "zero two hundred Romeo". Local time is designated as zone J or "Juliett". "1200J" ("twelve hundred Juliett") is noon local time.

"This is a list of time zone names" should likely be changed to something more like "This is a list of military designations for given UTC offsets".
