[IMPALA-1773] Implement TIMESTAMP WITH TIME ZONE data type

• Type: New Feature
• Status: Open
• Priority: Minor
• Resolution: Unresolved

• Component/s: Backend
• Target Version: Product Backlog

Description

Current implementation of timestamp does not give user an option to store the timezone information. This is not convenient in many applications as apps are forced to compute the time corresponding to their timezone unnecessarily using the from_utc/to_utc functions.
