Time-Zone Hover

Hover time strings to instantly see your local time, copy in ISO/12h/24h, and control sites individually.

Read global times at a glance. Time-Zone Hover converts dates and times on any webpage into your local time the moment you hover them — without changing the original text. One-click copy lets you paste timestamps in ISO-8601, 12-hour, or 24-hour formats. Keep it lightweight, private, and distraction-free. Key features ・Instant local-time tooltip on hover (non-destructive overlay) ・One-click copy in ISO-8601 / 12-hour / 24-hour (configurable default) ・Per-site control to enable/disable where you need it ・Clean, accessible UI designed for fast reading Pro (one-time upgrade) ・Optional inline annotations after times (e.g., → 05:00 JST) ・Per-site default time zone when a site omits TZ info ・Exclude rules (e.g., code, pre) to avoid false positives ・Settings export / import for quick backups Privacy ・No data collection. No external requests. Everything runs locally in your browser; settings are stored only in chrome.storage.local. Permissions ・Minimal: storage only. Host permissions are optional and can be granted per site. Great for Engineers, PMs, researchers, and anyone who reads across multiple time zones (PST/EST/CET/JST/UTC) and needs the correct local time instantly.
