Sync the clock of a Linux embedded device with a PC

1

I have an embedded device running Ubuntu 14 and I want to sync its clock. The problem is that the device does not have internet and the setup is like this:

enter image description here

The embedded device is connected to a PC using Ethernet cable. The PC can SSH to the device and bring-up a terminal. With this assumption that the PC's clock is correct/synced, how can I sync the clock of the embedded device with the PC?

One possible solution that I thought of is to run a 'proxy server' on the PC and connect the embedded device to the Internet through the proxy. Then I can run ntp to sync the clock. The problem is that I can not run a 'proxy server' on the PC (due to some admin issues), so this solution is not doable for me.

Can you run ntpd on the PC? Then the embedded device can sync with the PC directly. I know you can run ntpd as non-root user ntp, so I guess you can modify it to run under your user account as well (if the same admin issues prevent just installing ntpd). – dirkt – 2016-11-16T07:51:48.990

Use ssh's builtin socks proxy feature: ssh -D 1080 ...,, then you can access the whole internet from the embedded device via tsocks.
