How to get a timestamp for my end node which is a STML082?

I need to know, is there any specific command(Like a AT Command) to get a timestamp from any network server or gateway for the end device STML082?

Is there any API we can find in the "STM32 Cube Expansion" stack to implement it? If there, then where in the stack can we find it or what changes we need to do in the stack?

Thank you.
