Longest Uptime?

I know. Longest uptime is silly, macho, pointless stuff... but I ran across an old SunOS 2.6 box that had been up for 387 days. It had been hacked. The only reason it was not an open mail relay is that /var was full. So, I thought to myself, "I bet I could run an OpenBSD box for that amount of time or longer without getting hacked and without doing much to it." Just wondering what's the longest OpenBSD uptime some folks on misc have seen?

Thanks
