> Related to CALCITE-1623.
> At query preparation time, Calcite uses a Calendar to hold the value of DATE, TIME, TIMESTAMP literals. It assumes that Calendar has a UTC (GMT) time zone, and bad things might happen if it does not. Currently, we pass the Calendar object with user timezone from Hive. We need to pass it with UTC timezone and make the inverse conversion when we go back from Calcite to Hive.
