It's in the profile blob.

This SQL query calculates the 'time entitled on the account' by summing up the time played in minutes across all characters on an account, so you may be able to adapt it for your needs:

select sum(ascii(substring(profile, 237, 1)) + (ascii(substring(profile, 238, 1)) * 256) +
          (ascii(substring(profile, 239, 1)) * 65536) + (ascii(substring(profile, 240, 1)) * 16777216))
          from character_ where account_id = %i;
