Yes, dido what Orv said. I checked the code, there's a statement:
next if $uptime - $age > 86400;
The 86400 is the seconds in 24 hours, and this perl code statement skips this entry in the history and thus it is not saved further to be reported. However, this code is called when there is a change of the reported hosts on the network that OLSR receives. I suspect if there is a small mesh island and no mesh node or other change is propagating around, this history could stay for a while until it is triggered. Certainly on a very large network, like in SoCal, count on this history going away very close to the 24 hour mark.
