quicksheet-worldtm 🌍

Multi-timezone world clock extension for QuickSheet — your team's timezones at a glance on your desktop wallpaper.

Features

• 40+ timezone aliases — use NY, London, PST, or full IANA IDs like America/New_York
• Business hours indicator — 🟢 business hours, 🟡 early/late, 🔴 off hours
• Time-of-day icons — 🌅 morning, ☀️ afternoon, 🌆 evening, 🌙 night
• Fuzzy matching — type a city name and it finds the closest timezone
• Zero network calls — pure local System.TimeZoneInfo, works offline
• Default view — shows UTC, New York, London, Berlin, Tokyo, Sydney with no params

Install

In any QuickSheet cell, type:

ext: github:Deskworks/quicksheet-worldtm

QuickSheet clones the repo, reads the manifest, and registers the worldtm prefix.

Usage

worldtm: London, Tokyo, NY,5,8
worldtm: PST, CET, IST, JST,5,6
worldtm: America/New_York, Europe/Berlin, Asia/Shanghai,5,5

Important: The last two comma-separated numbers are always the output grid dimensions (columns, rows). Without them, QuickSheet may not allocate enough space for the output. Always append ,<cols>,<rows> after your timezone list.

Minimal examples

Cell content	Description
worldtm: London, Tokyo, NY,5,8	3 timezones, 5 columns × 8 rows
worldtm: PST, CET, IST, JST,5,6	4 timezones, 5 columns × 6 rows
worldtm: ,5,8	Default timezones (UTC, NY, London, Berlin, Tokyo, Sydney)
