And how do you do that?
I don't see that on my iPod Touch.System preferences > Date & Time and check the box for "Set time & date automatically" using Apple's time server.
It's not going to be on your iPod touch, it is on your mac. And when you sync your touch with the mac, it will update the time settings for you.
