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.
dpkg-reconfigure locales
Or its equivalent for modified armbian. See /etc/default/locale and
https://www.debian.org/doc/manuals/debian-reference/ch09.en.html#_customized_display_of_time_and_date
"9.3.4. Customized display of time and date" and "9.5.5. System and
hardware time". I hope, no applications rely on specific locale while
parsing time or numbers.
echo "$TZ"

but ignore most of its content, use zone identifiers like America/New_York
This device may have rather outdated tzdata package.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.
