dotnet-timezone

.NET timezone handling guidance for C# applications. Use when working with TimeZoneInfo, DateTimeOffset, NodaTime, UTC conversion, daylight saving time, scheduling across timezones, cross-platform Windows/IANA timezone IDs, or when a .NET user needs the timezone for a city, address, region, or country and copy-paste-ready C# code.

This skill ships only metadata — no inline instructions. See the source repo for details.

Install this skill

One command (all agents)

Runs the npx skills CLI which auto-detects every AI coding agent you have installed (Claude Code, Cursor, Codex, OpenCode, Windsurf, Copilot, and 51 more).

npx skills add https://github.com/github/awesome-copilot

Alternative: shorthand form

npx skills add github/awesome-copilot

Install to a specific agent

Pick the agent you use. The CLI writes the skill to that agent's standard skill directory.

npx skills add github/awesome-copilot --agent claude-code

npx skills add github/awesome-copilot --agent cursor

npx skills add github/awesome-copilot --agent codex

npx skills add github/awesome-copilot --agent opencode

npx skills add github/awesome-copilot --agent github-copilot

npx skills add github/awesome-copilot --agent windsurf

Manual install (no CLI)

Prefer to skip the CLI? Clone the repo and drop the skill folder into your agent's skills directory.

git clone https://github.com/github/awesome-copilot.git

cp -r awesome-copilot ~/.claude/skills/

For other agents, replace ~/.claude/skills/ with their skill directory — see the full list.

Use it

Once installed, ask your agent to "use the dotnet-timezone skill" or describe what you want (e.g. ".NET timezone handling guidance for C# applications. Use when working with TimeZ"). Most agents auto-discover the skill from its SKILL.md description — no slash command needed.

Requires: Node.js 18+ for npx skills. Skill files are MIT-style permissive by default — check the source repo for the actual license.
