UYT — Uruguay Standard Time
UYT is Uruguay Standard Time, 3 hours behind UTC. It is a fixed offset: unlike a time zone, it does not change with the season — the zones that use it switch to a different abbreviation instead.

Why UYT is not an identifier
UYT is shorthand, not a standard. There is no registry of time zone abbreviations, no authority that assigns them, and nothing preventing two regions from adopting the same three letters — which is what makes codes like IST and CST unusable without context.
For anything a machine will read — a calendar invitation, a database column, an API response — use the IANA identifier of the zone (America/Montevideo, for example) or an explicit UTC offset alongside the date. The identifier survives a change in the law; UYT and its 3 hours offset do not.

Which time zone should I use instead of UYT?
Use an IANA identifier — America/Montevideo for Uruguay Standard Time — or state the UTC offset with the date. Abbreviations are not identifiers: they are not unique, they are not registered anywhere, and half of them change with the season. Calendar software resolves this automatically when you pick a city rather than typing letters.
