+# Gitea Accessibility Fix - R4: Time Elements
+
+WCAG 1.3.1: Relative timestamps lack machine-readable fallbacks.
+
+## Fix
+
+Wrap relative timestamps in `<time datetime="...">` elements.
+
+## Files
+
+- `custom/templates/custom/time_relative.tmpl` - Reusable `<time>` helper
+- `custom/templates/repo/list_a11y.tmpl` - Explore/Repos list override
+
+## Deploy
+
+```bash
+cp -r custom/templates/* /path/to/gitea/custom/templates/
+systemctl restart gitea
+```
+
+Closes #554
