world-clock
mohitagw15856/pm-claude-skills
From the author
Get the current time anywhere and convert between time zones with zero API keys — timeapi.io via curl (worldtimeapi fallback), plus the DST-safe meeting-window math. Use when asked what time is it in a city, convert 3pm my time to Tokyo, find a meeting slot across time zones, or what's the UTC offset somewhere. Produces the local time(s), the conversion with DST handled by the API not by memory, and the overlap window for scheduling questions.
