I am a programmer working on embedded linux,

On my device, I need to set time everytime when I want to use it to check my program.

Is there any command or script which sets time from some Internet timeserver everytime?

Thanks.

Most likely which ever linux disto your working on has a NTP package which will allow you to sync with any pulic NTP server

Tutorial for ubuntu(should be similar in other distros):

You will have to have the ntp package installed.

If ntp is running:

ntpdate -u pool.ntp.org

otherwise without ntp running, I believe it would be:

ntpdate pool.ntp.org
