-----------------------------------
Summary: Add support in Avatica for TIMESTAMP WITH LOCAL TIME ZONE
Key: CALCITE-5500
URL: https://issues.apache.org/jira/browse/CALCITE-5500
Project: Calcite
Issue Type: Improvement
Components: avatica
Reporter: Will Noble
This is closely related to CALCITE-5446 but tracks the changes required in
Avatica. This is where time zone conversion happens when the client invokes a
getter method on a {{ResultSet}}. Here are the intended semantics for
{{TIMESTAMP}} and {{TIMESTAMP WITH LOCAL TIME ZONE}}:
{{TIMESTAMP}}:
* {{getString()}} -> Always returns the same string no matter the client's time
zone
* {{getTimestamp()}} -> Subtracts the zone offset from the instant, so
rendering the instant to a string in the client's time zone produces the same
result as {{getString()}}
{{TIMESTAMP WITH LOCAL TIME ZONE}}:
* {{getTimestamp()}} -> Always returns the same instant no matter the time zone
* {{getString()}} -> Adds the zone offset to the instant before rending it to a
string, so rendering the result of {{getTimestamp()}} in the client's time zone
produces the same result as this.
