I might had uncover another bug when testing it as I was using an adhoc
cluster with only 1 node to test it.

in this scenario the cluster time also stop getting updating resulting in a
"frozen" age.

from show_node.php, lines 68 to 71

# Compute time of last heartbeat from node's dendrite.
$clustertime=$cluster['LOCALTIME'];
$heartbeat=$hostattrs['REPORTED'];
$age = $clustertime - $heartbeat;

right, if there are more nodes in the cluster, it will be correct.
