WTH? Where is that false 12 hour offset coming from?There is no 12 hour offset. One is being reported in 24-hour time, and the other in 12-hour time (it says "PM"), because of different locale definitions.

Or its equivalent for modified armbian. See /etc/default/locale and

"9.3.4. Customized display of time and date" and "9.5.5. System and

This device may have rather outdated tzdata package. The database is
updated several times a year. Maybe your time zone has not changed since
that version was released.
I would not be surprised if this box does something fancy like sending a request to some GeoIP database and setting timezone accordingly to received response.
