The UTC time zone is sometimes denoted by the letter '''Z''' – a reference to the equivalent nautical time zone ([[GMT]]), which has been denoted by a '''Z''' since about 1950. The letter also refers to the "zone description" of '''zero''' hours, which has been used since [[1920]]. See [[time zone#History|time zone history]]. Since the [[NATO phonetic alphabet]] and [[amateur radio]] word for '''Z''' is "Zulu", UTC is sometimes known as '''Zulu time'''. This is especially true in aviation, where Zulu is the universal standard.<ref>[http://wwp.greenwichmeantime.com/info/timezone.htm Military & Civilian Time Designations]</ref> This ensures all pilots regardless of location are using the same [[24-hour clock]], thus avoiding confusion when flying between time zones.<ref>Williams, Jack.
