question on the behavior of system setting for user password expiration date

Summary:

I have a question on the behavior of system setting for user password expiration date.

Content (required):

If this system setting is extended, will the system apply the new setting to all users immediately or not until after the original expiration date applied to a user has been passed? I am almost certain that the new setting applies immediately, but would like to know if anyone knows definitively.
