{{Main|List of time zone abbreviations}}

Time zones are often represented by alphabetic abbreviations such as "EST", "WST", and "CST", but these are not part of the international time and date standard [[ISO 8601#Time zone designators|ISO 8601]]. Such designations can be ambiguous; for example, "CST" can mean (North American) [[Central Standard Time]] (UTC−06:00), [[Cuba Standard Time]] (UTC−05:00) and [[China Standard Time]] (UTC+08:00), and it is also a widely used variant of ACST ([[Australian Central Standard Time]], UTC+09:30).<ref>"[https://www.timeanddate.com/time/zones/ Time Zone Abbreviations – Worldwide List]", Timeanddate.com. {{Webarchive|url=https://web.archive.org/web/20180821101900/https://www.timeanddate.com/time/zones/ |date=August 21, 2018 }}.</ref>
