system.timezone=Asia/Seoul on your recalbox.conf file
Of course, I set system.timezone = Asia / Seoul on recalbox.conf file.
So, when the internet is connected, the recalbox menu displays the correct local time.
However, when I boot it off-line, it displays about 9 hours faster.
I can then access the recalbox 's root user on the Linux system and modify the time, but the time on the rtc clock keeps the original local time.
The time on the rtc clock is retained by reboot but the recalbox does not use it. When I boot off-line, the menus in the recalbox display 9 hours faster than the rtc clock.
This is not my setting mistake, but the program problem of the recall box is obvious.
Thank you for your kindness.
