Description

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. Bad things probably happen if it does not. We should check, and throw IllegalArgumentException if not.

(For the record, Calendar is not used at run time. Those values become int or long, or Integer or Long if nullable.)
