How does PhoneBurner determine the Time Zone for a contact or the Local time to display in the contact manager?
PhoneBurner will try to use the city/state provided in the address first and if that isn’t sufficient, it will look at the phone number area code. If it still can't determine the information, then the zip code and finally the IP address if available. If nothing works, we will mark them as “America/Chicago”, i.e. Central Time.
This will apply when the contact is imported, but if the information is manually changed in they system, it will not update the time zone/ local time information.
If you are able to update the contact in your import file and then re-import and screen for duplicates with the option selected to update the duplicate files, you may be able to get the timezone/local time to update.
When a call is made, we check the timezone for each phone number( area code) at the moment the call is about to be made (to determine if the local time is within the allowed call times). This is separate from the Time Zone/ Local Time calculation.
