To the right of the filters:

• Total entries — count of non-blank lines in the visible (filtered) subset
• First entry — timestamp of the earliest entry in the visible subset
• Most recent — timestamp of the latest entry in the visible subset

Click on either “First entry” or “Most recent” to toggle between relative (3 minutes ago) and absolute (Wed, Apr 22 17:00) format. The choice is remembered per file.

Relative thresholds:

Elapsed	Display
0–14 s	just now
15–59 s	less than a minute ago
1–59 min	N minute(s) ago
1–23 h	N hour(s) M minute(s) ago (minutes omitted when 0)
≥ 1 day	N day(s) M hour(s) ago (hours omitted when 0)

The most-recent label auto-refreshes every 30 s so “2 minutes ago” walks forward as wall-clock time advances.
