EOS 6D Firmware Version 1.1.3 released by Canon
This firmware update fixes a phenomenon in which the Date/Time/Zone settings screen appears on the LCD display, after the user has already configured these settings. The values for the Date/Time settings may reset if the backup functions which retain those values do not perform properly.
Even if the camera does not show this phenomenon now, it may in the future. Accordingly, we recommend that you update the Firmware in the camera to version 1.1.3 as soon as possible.
Firmware Version 1.1.3 is for cameras with firmware up to version 1.1.2. If the camera’s firmware is already Version 1.1.3, it is not necessary to update the firmware. Before downloading the firmware update for your camera, please review the instructions thoroughly.
