Having same problem with stats, the only way to get the stats correct on both sides is to advance the clock +24 hours. When I do this I see this "19 We have guests online 12.02.2009 15:24:58" the time is correct the date is wrong, i day a head.
I also don't see 20 visitors/bots, only 1 & that's my IP address in real time.
Joomla's module will say 10 guess, yours says 20 guest currently online, who's right?
Is there a way to change the date format to mm/day/year for the Yanks?
