[jira] [Comment Edited] (IGNITE-5384) JDBC Driver: implement ResultSet#getDate(int, Calendar)

--------------------------------------------------------------

Looks like we must not implement date conversion explicitly because Ignite store a date as {{long millis}} gathered from {{Date}}.

JDBC javadoc says (for all methods of the {{ResultSet}} that contain Calendar argument):
{quote}
This method uses the given calendar to construct an appropriate millisecond 
value for the date if the underlying database does not store 
timezone information.
{quote}

So, Ignite store timezone information because the UTC milliseconds are stored.
[~vozerov], please provide your thoughts.
