Cached TimeZoneInfo access for common continental US zones and IANA/CLDR identifier resolution through TimeZoneConverter.

Installation

dotnet add package Soenneker.Utils.TimeZones

Common US zones

using Soenneker.Utils.TimeZones;

TimeZoneInfo eastern = Tz.Eastern;
TimeZoneInfo central = Tz.Central;
TimeZoneInfo mountain = Tz.Mountain;
TimeZoneInfo pacific = Tz.Pacific;
TimeZoneInfo arizona = Tz.Arizona;

The properties are initialized lazily and then reused. They resolve these IANA zones through TimeZoneConverter:

Property Source identifier Daylight saving time
Eastern America/New_York Observed
Central America/Chicago Observed
Mountain America/Boise Observed
Pacific America/Los_Angeles Observed
Arizona America/Phoenix Not observed

TimeZoneInfo.Id may be an IANA identifier or its Windows equivalent depending on the operating system. Use TimeZoneInfo conversion APIs instead of comparing the returned Id with a hard-coded platform-specific value.

Resolve an identifier

TimeZoneInfo zone = Tz.FromCldr("Europe/Paris");
DateTimeOffset local = TimeZoneInfo.ConvertTime(instant, zone);

The five built-in US zones return their shared property instances. America/Denver and America/Boise both return Tz.Mountain, whose source identifier is America/Boise. Other identifiers are resolved by TZConvert.GetTimeZoneInfo and cached by the exact input string.

Unknown or unsupported identifiers throw the exception produced by TimeZoneConverter. The fallback cache has no eviction, so do not call FromCldr with an unbounded stream of user-controlled identifiers without validating or constraining them first.

Time-zone rules come from the operating system and TimeZoneConverter mappings. They can change as governments and time-zone databases change; store the original zone identifier when future recalculation matters.

Call the static Tz members directly; no dependency-injection registration is required.
