1. Register a system in a manner that causes RHQ to have an unknown ("grey") status icon.
2. In the summary tab for that resource, hover over the grey "?" icon.
3. View the "Availability" line.
Resource has been since: 12/31/69, 7:00:00 PM, EST
MTBF: Mean Time Between Failures over the known resource lifetime.
Serendipitously enough, the icon that appears (at least on FF3/linux) is a question mark within a diamond. However, I don't suspect that was intent. Generally I think that tends to show up for non-renderable characters.
Viewing the page source, the character is "�"
According to http://www.w3.org/TR/html4/sgml/entities.html
"Character 65533 (FFFD hexadecimal) is the last valid character in UCS-2. 65534 (FFFE hexadecimal) is unassigned and reserved as the byte-swapped version of ZERO WIDTH NON-BREAKING SPACE for byte-order detection purposes. 65535 (FFFF hexadecimal) is unassigned."
So I am guessing some sort of null value is showing up here, inadvertently.
