Facebook Full Timestamps
Display exact, full timestamps directly on Facebook posts without hovering.
About this script
Eliminates the annoyance of hovering over relative timestamps (e.g. '1h', '2 hrs') on Facebook. Automatically reveals and displays the full, localized publication date and time alongside post links in a clean, native-styled badge. Supports one-click timestamp copying and light/dark themes.
Features
- Full Khmer timestamp support: formatted as ααααα’αΆαα·ααα ααΈα‘α αααααααΆ ααααΆαα’α α’α¦ ααααα α¦:α α₯ AM or Khmer Short (α’α α’α¦-αααααΆ-α‘α’_α α¦:α₯α¨).
- Replaces relative timestamps (e.g. '4h') with clean custom dates formatted as YYYY-mmm-DD_HH:mm (e.g. 2026-Sep-12_06:58).
- Dedicated Tampermonkey quick-switch commands for Khmer and English timestamps.
- Display mode toggle: switch between replacing original relative time or showing side-by-side.
- Matches Facebook's native typography with Kantumruy Pro & Inter font support.
- Preserves the original post permalink anchor navigation and right-click behaviors.
- Click-to-copy: Click any timestamp badge to instantly copy the exact date to clipboard.
