This is a list of time zones as used by the U.S. military, Chinese military and others. The names are based on the NATO phonetic alphabet (with two spelling changes: Alpha for « Alfa », Juliet for « Juliett »).
Going east from the prime meridian at Greenwich, letters Alpha through Mike (skipping « J », see below) are used for the 12 time zones with mainly positive UTC offsets until reaching the International Date Line. Going west from Greenwich, letters November through Yankee are used for zones with negative time offsets.
