Question:
Why does the Call Date and Call Datetime of a Call not match in CRM online?
Example: The Call Date of a Call is 2017-08-30, but the Call Datetime is 2017-08-31 06:30.
Answer:
The Call_Datetime_vod__c field stores the datetime value in the GMT timezone. The CRM for iPad application and the Online Visualforce (VF) page converts this back to the user's timezone. In this way, users with different timezones can see the same time.
When the date from the Call_Datetime_vod__c is stamped to the Call_Date_vod__c, it takes the date period that is already converted to the user timezone. This is the reason why the Call Date points to a day before (or after) the Call Datetime.
Currently, this is working as designed.
