odd selftest log on an OCZ VERTEX PLUS SSD

Hi,

I have set up smartd and have scheduled a daily short self test and weekly
long self test of an OCZ VERTEX PLUS SSD. I have an issue where the
"lifetime(hours)" column in the selftest report appears incorrect (see
below). Interestingly, querying the power on hours attribute shows the
correct figure of 5555 hours.

Any advice on why the hours value is incorrect in the self test logs would
be appreciated.

Regards,
Richard
