Date: 2018aug14 OS: Linux Q. Linux: How can I accurately set the time on my Linux box? A. Its best to run a time service all the time. But if you want to correct the time right away or its off by a lot you can do:

ntpdate <ntp-server>

For example:

ntpdate time.google.com

You can see a list of more NTP servers here: https://www.ntppool.org/en/ The ntpdate command is in package ntpdate on most distros.
