Docker ntpdate

This just runs ntpdate on your server. You must run this with "--privileged" for it to be able to update the time.

Pretty much made this to run on boot2docker

Example

docker run --privileged --rm cpuguy83/ntpdate

Pass in a custom server as such

docker run --rm --privileged cpuguy83/ntpdate 0.us.pool.ntp.org

Default is "0.pool.ntp.org"
