Final answer:
Contact Local Time Zone is usually based on the customer profile, but systems may allow customer override. Existing cases could have the time zone updated from the customer profile. The statement that it is not based on the customer profile is typically false.
Step-by-step explanation:
Regarding the question of which is true about Contact Local Time Zone, it depends on the specific system or software being referenced, as different Customer Relationship Management (CRM) systems might handle this differently. However, in many systems, Contact Local Time Zone is typically derived from the customer profile where a customer's contact information is stored. This time zone information is used by businesses to ensure that they contact customers at appropriate local times. Some systems may allow customer override, where the customer can manually set the time zone they prefer, instead of it being set automatically based on their profile or geographical location.
It is false to say that Contact Local Time Zone is not based on customer profiles because generally, it is initially set based on the location in the customer's profile, ensuring that communication happens at reasonable hours for the customer. When considering case updates, for existing cases, the local time zone may indeed be updated based on the customer's profile or any subsequent changes that might have been made manually by the customer or by customer service representatives.
