The current version does not print the ETA on my brand new Anet A8 (HW 1.5).
I can see the Message in the Octoprint console (xxx ETA: HH:MM:SS xxx) but the display only shows "ETA".
While this problem may not be fully on your side but rather on Anet's side (I did not flash the latest Marlin SW yet over the original FW on the board) you may still want to look into it.
