[OpenWrt-Devel] time command detect fail on centos

[李国]

Hi Etienne Champetier,

You are right.
CentOS 7 is ok, but CentOS 6 fail.

on CentOS 7
$ sh -c 'time --version'
GNU time 1.7

but on CentOS 6
$ sh -c 'time --version'
sh: --version: command not found

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

Thanks!
