Hello,

my Cubitruck with Armbian 23.8.1 Bullseye has the false Time and i can't change this.

i don't know who is the problem.

"date" says me "Mo 9. Feb 19:24:06 CET 2026" but now we have 05:26, when i set date with "sudo date -s "2026-02-09 05:26:00", it looks like it will be override in the next moment, then "date" says

 sudo date -s "2026-02-09 05:26:00"
Mo 9. Feb 05:26:00 CET 2026
root@cubietruck ~ > date
Mo 9. Feb 19:26:27 CET 2026
