smartctl: power on hours on a samsung disk

Does anyone know how to read the smartctl value on a Samsung SP 1604N 160GB
pATA disk? I always get

9 Power_On_Hours 0x0032 098 098 000 Old_age
Always - 1325263

and I'm pretty sure the disk didn't run for 150 years yet.
Tried -F samsung{,2} with smartmontools 5.37-6~bpo40+1
