Soenneker.Extensions.TimeZoneInfos

Map the four continental US time-zone IDs to stable, daylight-agnostic abbreviations.

Installation

dotnet add package Soenneker.Extensions.TimeZoneInfos

Usage

using Soenneker.Extensions.TimeZoneInfos;

TimeZoneInfo timeZone = TimeZoneInfo.FindSystemTimeZoneById("America/Chicago");
string abbreviation = timeZone.ToSimpleAbbreviation(); // "CT"

The mapping recognizes both Windows and IANA identifiers:

Windows ID	IANA ID	Result
`Eastern Standard Time`	`America/New_York`	`ET`
`Central Standard Time`	`America/Chicago`	`CT`
`Mountain Standard Time`	`America/Denver`	`MT`
`Pacific Standard Time`	`America/Los_Angeles`	`PT`

The comparison is case-insensitive. Other zones return "Unknown".

The result deliberately does not distinguish standard time from daylight time: New York returns ET, not EST or EDT. This method does not inspect an instant or calculate an offset; use TimeZoneInfo.GetUtcOffset() when the date-specific offset matters.
