After entering "\utc 2023 05 01 05:00:00"?into the command box, it did change the date/time in the title bar, but no change after a restart, and I2C is enabled.
Thanks for what you have done so far JJ.? If it's not fun, then take a break, that's what I'm going to do this weekend.?
Have a good one with your family JJ.
This code expects the I2C bus to be kernel I2C interface. Make sure you have one of the dtoverlays in /boot/firmware/config.txt
For loading the I2C Bit-Banged (BB) driver in the appropriate sBitx pins, with kernel RTC clock driver loaded (for use as system clock, this is what I use):
dtoverlay=i2c-rtc-gpio,ds1307,bus=2,i2c_gpio_sda=13,i2c_gpio_scl=6

change UTC to local utc (UTC1 UTC2 UTC3)
setenv("TZ", "UTC1", 1);
