Hashing Functions

[itPro]

A debate has come up recently and I was wondering what others thought about it. The debate is about whether or not it increases security to add content to user input. Here's the two scenarios:

1.
- A user registers a password.
- The password is hashed.
- The hash is stored in the database, along with the username.

- When comparing passwords to user input later, the user inputs a password.
- The password is hashed.
- The new hash is then compared against the hash stored in the database to determine if the user authenticates.

OR

2.
- A user registers a password.
- The date and time is stored in the database.
- That date and time that is stored is then added to the input.
- A hash is created from the combination of the input and the stored date and time.
- The hash is stored in the database, along with the username.

- Later, a user enters input.
- The input is then paired with the date and time that is found by searching for the username.
- The input and date / time combination is then hashed.
- The new hash is then compared to the hash stored in the database.


My argument is that adding content to the user's input before hashing it will prevent dictionary attacks, (especially if the date/time fields are stored in a separate table in a separate database.)

What are your thoughts?
