Seems a too small register was used for the $uptime calculations, it wraps back to 0 around 49 days, $ticks still works cool

//echo 4 $ $+ ticks = $ticks and $ $+ uptime(system, 1) = $uptime(system, 1)

gives me: $ticks = 29660830 and $uptime(system, 1) = 8hrs 14mins 20secs

MS uptime utility (fired up a moment later) gives me \\RON has been up for: 50 day(s), 1 hour(s), 13 minute(s), 12 second(s)
