Managing date/time [clock] on offline devices

Thanks. I found the Serial tutorial post and I can get connected now, but it seems I’m limited to entering a small set of single characters, like ‘m’ to get MAC address or ‘i’ for device ID. That works.

But I can’t figure out how to send any kind of commands, like setTime(). I tried Shell menu | New Command option but I’m hitting dead ends. I can’t find a tutorial for this stuff anywhere. Do I need to preface setTime() with something or wrap it in some other code?
