/var/run/utmp system startup/shutdown records are not written so who -b shows
nothing although who is included in cygwin Base package coreutils
/proc/uptime shows number of seconds wall time since startup, and number of
seconds idle time since then e.g.:
$ cat /proc/uptime; date -d"now - `cut -d' ' -f1 /proc/uptime` seconds"; uptime
