8.1.5.0 64-bit unable to change timezone it is grayed out

I am unable to change the time zone; it is grayed out and stuck on UTC. I usually have it set to my local time zone. Can anybody suggest a fix for this?

  • Access Time Zone Settings: Open the Control Center, go to Tools > Options, and select General from the left-hand menu.
  • Change Time Zone: In the Properties section, a dropdown will allow selection of the desired time zone.
  • Save and Restart: Click OK to save changes and restart NinjaTrader for the new time zone to apply.
