2 numbers in /proc/uptime??
 

why are there two numbers in the /proc/uptime??

both seemed to calculate uptime. Not sure relative to what though.
=============================================
Also one behaviour I find it really weird the time seemed to be off between the two.

cat /proc/uptime ==> 96.50 62.42 (difference of 34.08)
cat /proc/uptime ==> 349.40 315.14 (difference of 34.26)
cat /proc/uptime ==> 456.79 421.59 (difference of 35.20)
cat /proc/uptime ==> 695.91 660.20 (difference of 35.71)

The first number is the uptime in seconds... The second is something to do with time in idle processes or somesuch... Check man proc for more maybe.

/proc/uptime - 2 numbers
 

/proc/uptime
This file contains two numbers: the uptime of the system (seconds), and the amount of time spent in idle process (seconds).
