How do I tell a server's uptime

I have used UNIX mainly HPUX and Mac OS X for a number of years and am now using Solaris 9 and I was just wondering what is the easiest way to find out a servers uptime? I would usually use the uptime command on a Mac OS X box but am not sure that this command will work on Solaris 9. Any help would be appreciated.

Have you tried 'uptime'? ;-)
