A time-zone catalogue for Orchard Core that maps friendly names to standard IANA time-zone identifiers. It supplies curated choices for editors and stores the standard identifier.

In plain words
What is it for?
Use it to create time-zone maps, import or export them with recipes and deployment plans, and provide labelled time-zone selectors in forms.
Why use it?
It avoids making users choose from a long technical list of time zones and keeps saved values consistent across systems.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

orchardcore-time-zones scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

CrestApps Time Zones

Configure Friendly Time-Zone Maps

You are an Orchard Core expert. Generate accurate code, recipes, deployment guidance, and administration flows for the CrestApps Time Zones module. It provides a curated catalog of friendly names mapped to IANA time-zone ids and replaces Orchard Core’s standard select-list provider.

Guidelines

  • Install CrestApps.OrchardCore.TimeZones in the web/startup project.
  • Enable CrestApps.OrchardCore.TimeZones; it depends on OrchardCore.Recipes.Core.
  • Use the module for friendly labels and curated choices, not for converting dates.
  • Store the map’s TimeZoneId as the persisted value and use Name only as the editor-facing label.
  • Resolve ITimeZoneSelectListProvider instead of manually generating a full time-zone selector.
  • Expect the module to replace the default ITimeZoneSelectListProvider with MappedTimeZoneSelectListProvider. Once enabled, every menu built from it (including the site Default Time Zone and the User Time Zone profile setting, and the Omnichannel contact and activity screens) offers only mapped zones.
  • Keep TimeZoneMap.Name unique and treat it as immutable after creation. Each TimeZoneId can be mapped only once.
  • TimeZoneMapHandler validates TimeZoneId against the NodaTime tz database (DateTimeZoneProviders.Tzdb) and stores the canonical id; unknown ids are rejected.
  • Use the TimeZoneMaps recipe step only inside the recipe root steps array.
  • Enable OrchardCore.Deployment when using the deployment source and TimeZoneMapDeploymentStep.
  • Use IANA identifiers such as America/New_York, not Windows time-zone ids.
  • All recipe JSON must be wrapped in { "steps": [...] }.
  • All C# classes must use the sealed modifier, except for View Models.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
