I read the manual and it said to insert %n for a new line in the tooltip, but whenever I did windows xp treated it as a space or something..
ChronosToolTip "Date: %A, %B %#d, %Y %n Time: %#I:%M:%S %p %n Uptime:%Ud days, %UH hours, %UM minutes, %US seconds."
produced this:

Am I missing some syntax or does this just not work?

Chronos is dead. Use (x)Label instead
