The Glycine Airman, the first watch capable of tracking two 24-hour time zones, has been used extensively in commercial and military aviation, as well as in spaceflights; notable examples include its use by United States Air Force pilots during the Vietnam War and astronaut Pete Conrad during the Gemini 5 and Gemini 11 spaceflights.
Such designations can be ambiguous; for example, "CST" can mean China Standard Time (UTC+08:00), Cuba Standard Time (UTC−05:00), and (North American) Central Standard Time (UTC−06:00), and it is also a widely used variant of ACST (Australian Central Standard Time, UTC+9:30). Such designations predate both ISO 8601 and the internet era; in ...
