script to capture time spent

[M Zubair_1]

Can someone help me in writing a small shell script to capture the "time" spent by a command?
I have to do some data migration from one file system to another. Planning to use tar (copy/extract in one command). Same process will be applied to two different boxes. The two servers have more or less the same file systems. I want to know how long each file system take so that I can plan exact down time for the other box.
Thanks in advance!
