Difference in timings with strace and time comman

I am trying to do some profiling of one of the third part tool I am likely
to use for which I do not have source code.
I tried to run it using time command and later with strace.
I noticed that system time reported by time is o where close to the sum of
the system call times reported stace.
Of course I have many read and write calls.
So here are my questions.
Does strace includes IO wait time in the timing reported in read?
And I presume time command does not and hence timing reported by time and
strace are completely skewed
Any help will be appreciated
