KUpTime

KUpTime is a light, free and simply to use software to retrieve system uptime.
It displays, in real time, how long your PC has been running since startup (uptime).
It also displays the date-time when your computer was started (boot time), the current date-time, the OS installation date-time and the OS installation time.
KUpTime can be minimized to the systray and display uptime & current date-time in the systray's tooltip.
