What is Zulu Time?
Zulu is the name professionals use for UTC, Coordinated Universal Time. The Z suffix comes from the NATO phonetic alphabet: the prime meridian sits in time zone Z, and Z is spoken as Zulu. It never shifts for daylight saving. 1400Z means 2 pm UTC everywhere on Earth, no exceptions.

HAM radio contact log
Freq: 14.250 MHz SSB
Time: 1430Z
Operators worldwide log contacts in UTC so nets and contests work across every timezone.
Military Time Zone Letters
NATO uses a phonetic letter for every UTC offset instead of abbreviations like "EST" or "PST". This eliminates ambiguity across nations, languages, and theaters of operations. Z (Zulu) is UTC+0, the universal reference. Letters A–M cover positive offsets east of Greenwich; N–Y cover negative offsets to the west. J (Juliet) is reserved for local time and not assigned a fixed offset.
