Hello Xiscu, The only reference nowadays inside the kernel for the uptime is the efective "uptime" variable accesible through /proc/uptime, it have the following definition:
uptime Wall clock since boot, combined idle time of all cpus To cover your use case, at least, is needed an other variable with the proper counter. As example, the simple solution can be something like this: rtime Efective running time. But I doubt that this will be implemented inside ther kernel. Apart, Tuptime would need a large refactoring. Thanks,
