    Easier yet with sed and date: 
    date -d @$(sed -n '/^btime /s///p' /proc/stat)

      My "date" here doesn't have a "-d" that works that way. Nor is @$(...) standard. I suspect you're coding full of linuxisms without realizing it, although in this context, it's fair since it was about a "linux" boot time.
