> 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.
