Re: Using "time" to assess browser start-up time
The output of time gives three things:
real time (total running time)
user time (time cpu spent processing code in user space)
sys time (time cpu spent processing code at kernel level)
So adding up user + sys will give you total time that the cpu was working on the application for. I think its the closest that youll get to working out the uptime, by default this would include time taken for the cpu to close the application too but if you use this method but manually cut the process off from the same terminal you ran the initial time command in (using ctrl+c) you should get a reasonably accurate result of how long the cpu spent opening the application.
