Choose another future_date_1 date (9 days instead of 10) to
make sure the expiration date will be between future_date_1
and future_date_2. Otherwise the expiration date might be
equal to future_date_1.
Also wait for 10 seconds before the password refresh in
test_pwd_expiration_date_update to prevent date equality.
