Setting the time on different devices

Open a terminal

You will need a terminal window open to access the Linux system.

Open up PuTTY.
In the default (Session) category, enter the IP address and port 22. Select SSH

3. To update the time without having to find the current time in timestamp format, run the following command. This pings google.com and gets the time from the response.

sudo date -s "$(curl -s --head http://google.com | grep ^Date: | sed 's/Date: //g')"

4. To update the time manually, first find the current time in a timestamp format. The current time in timestamp format can be found https://www.epochconverter.com/ or https://www.unixtimestamp.com/. Copy the seconds since Jan 01 1970 from the top area.

Then run the following command which will allow you to set the date on most systems.

sudo date -s @1598275106

If a system has an NTP server configured, that time will take immediate precedence after you submit the above command.

Some systems will not allow you to change the date time unless other system configuration options are changed, like the ZumIQ from Freewave.
