I want to know how much time is taken by Ubuntu 14.04 when we start it. So for this I have added the below line in rc.local



awk 'print int($1/3600)":"int(($1%3600)/60)":"($1%60)' /proc/uptime > /var/log/uptime.log


It is showing about 28 seconds. Can someone let me know how can I get more information about what steps are adding to this 28 seconds?
