Well, if I undertand correctly, the goal here is to get the time since
boot, generally since CLOCK_BOOTTIME was initialized, and this one
doesn't get updated during suspend (at wake up).

So this doesn't really fit here.
slstatus is already full of ifdefs (which I was opposed to), so why not
keeping it here anyway?
