-    - Accepts epoch seconds, ISO 8601 (`2023-11-14`, `2023-11-14T12:00:00`, `2023-11-14T12:00:00Z`, `2023-11-14T12:00:00+0100`), or space-separated datetime (`2023-11-14 12:00:00`)
-    - Auto-detects format and converts ISO 8601 to epoch via `bashunit::date::to_epoch`
-    - Mixed formats supported (one epoch, one ISO) in the same assertion call
-    - Fully portable across GNU and BSD systems
