Fixed the Last Seen column in the agents table to show relative time with abbreviated format and tooltip. **Changes made:** - Modified `server/templates/partials/agents_table.html`: - Line 87-89: Removed `data-date` attribute from the `<td>` element to prevent conflict with the global date formatting in `base.html` - Line 257-272: Updated `updateRelativeTimes()` JavaScript function to use abbreviated format: - Under 60 seconds: "X sec ago" - Under 60 minutes: "X min ago" - Under 24 hours: "X hr ago" - Under 7 days: "X days ago" - After 7 days: shows the date (YYYY-MM-DD) - Line 270-271: Added tooltip with full datetime in local time using `element.setAttribute('title', localDateTime)` **Issue discovered:** The global `applyDateFormatting()` function in `base.html` was processing all elements with `data-date` attribute and setting their textContent directly, which was overwriting the `<span class="relative-time">` structure. The fix was to remove the `data-date` attribute from agent cells so they are only processed by the agents table's own `updateRelativeTimes()` function. **Verification:** - Deployed to production at trckr.roboalch.com - Verified relative time display shows abbreviated format (e.g., "5 min ago", "13 min ago", "2 hr ago") - Verified tooltip shows full datetime in local time (e.g., "12/11/2025, 9:14:32 PM") - JavaScript updates every 30 seconds as expected
