Fix_User_Table timestamp replacement columns are off

The Timestamp columns are set as :
$access_column = 10;
$login_column = 11;

However, my schema is as follows for user:
0 uid
1 name
2 pass
3 mail
4 mode
5 sort
6 threshold
7 theme
8 signature
9 signature_format
10 created
11 access
12 login
13 status
14 timezone
15 language
16 picture
17 init
18 data

Thus I am updating my code to:
$access_column = 11;
$login_column = 12;
