I spent about two hours trying to figure out how to do that, but looks
like my ignorance when it comes to AT commands used by ESP, and the
ignorance when it comes to the SNTP protocol is simply deadly. All I got
was a few random characters, similar to other people trying to do the
same. I don't feel like reading the corresponding RFC right now, so
let's play WoT and listen to good old Prodigy.
