My roku tv has been showing the incorrect time and when I go into the system settings the time setting is missing completely.
Mine has Home>System>Time where I can set the timezone manually or automatically. I think, after that, the actual time is set with a network time server (like NIST). If you have that menu item like I do, and the timezone is set correctly, you should probably post the timezone it shows. (Also go to home>system>system update & post your software version. I'm 9.4.0 4200).
But that's my problem. I have no setting option for time at all. It's completely missing.
What is the current software version? (Roku will probably want that to help you. I'm just stabbing in the dark.).
I would also do the "check now" for a new update at that screen. I'd also try home>system>power>system restart. (That's the "reboot your computer" type of "who knows, maybe it will fix it" suggestion).
In home>system>advanced system, there is a "network connection reset." I might try that since the time comes from the internet. (But, if you can check for new software update, then your network must be ok.).
It's says it's up to date with the 9.4.0
I'll have to try your other suggestions. Thank you.
