for last kernels (from 2.6.22) you can read from file /proc/<pid>/stat, 14-17 values is
utime user mode jiffies
stime kernel mode jiffies
cutime user mode jiffies with child's
cstime kernel mode jiffies with child's

time <my command> gives the time taken for the command 'my command' to get executed...
the time for a running process can be found from ps -aux command..
