I would like to make a script that outputs only the real time value

I would like to make a script that outputs only the real time value from the time command so I can plot the results. For example time command outputs

real    1m0.001s
user    1m0.000s
sys  0m0.001s

I want to write a script that outputs

60.001

How do I get just real time value from ‘time’ command in seconds?

    If you’re using the Bash builtin time, set the TIMEFORMAT variable to %R:

    $ TIMEFORMAT=%R
$ time sleep 1
1.022
