strange time problem with bullseye

[hlyg]

my newly-installed deb11 for amd64 shows wrong time,  it lags behind 
correct time by 8 hours though difference between universal and local is 
ok.

i am normal user, i install only from main of deb11 plus wifi adapter 
firmware, though i don't install security update. i don't know where i 
can go wrong

but my deb11 for i386 on same machine shows correct time. i installed it 
long time ago

wifi connection is good, i suppose both correct time with server 
automatically
