Ok so let me try this again, if you have PDI then access below Abel Tutor account and consider Abel tutor as caller so caller's timezone is nothing but 'Timezone' field in Abel tutor record whereas caller location timezone is there in 'Location' field on Abel tutor record and as 'Location' is reference field pointing to 'cmn_location' table so if you open 'Location' record you will find 'Timezone' there as well so caller location timezone is that. In short both are not same. I hope that clears your doubt. Mark my answer as correct and close the thread.

Caller timezone:
Caller location timezone : Click on highlighted field , open record and see Timezone , that is nothing but caller location timezone.
