NTP to resetdate , time

I am a complete noob with BBB and Linux.

If I read it correctly I believe my BBB should auto set its time and date a short time after boot up
with something called NTP .

Mine doesnt seem to do that. I left it running over 1 hour and it still said the wrong time and date

Could someone explain step by step ( so a newbie can follow it) how to get it going please

Cheers
Don

There is already a discussion here where someone explains how they got it working…
