I put my laptop to suspend mode, woke it up later, and now it shows uptime some 23 hours (with uptime), which is obviously not true. I suspect uptime simply returns the difference between the timestamp at boot and now.
Is there a way to show uptime excluding time spent in low power modes like suspend and hibernate?
Please read carefully; this is not the usual uptime question.
I tend not to shut down my computer per se but instead put it to sleep. It makes boot times quicker and allows me to use WOL. The various 'uptime' methods (sysinfo, uptime.exe, Task Manager, etc) will show the time since the last full boot, which means time spent sleeping is factored in.
