I think it's easy to prevent the time indicator push-down in our side.
Calcite 1.3 changed the `ProjectJoinTransposeRule.INSTANCE` to `new
ProjectJoinTransposeRule( PushProjector.ExprCondition.TRUE,
RelFactories.LOGICAL_BUILDER);` instead of `new
ProjectJoinTransposeRule(PushProjector.ExprCondition.FALSE,
RelFactories.LOGICAL_BUILDER);`.
In order to change the default behavior of the rule, the only thing we need
to do is to create a new `ProjectJoinTransposeRule` with a custom
`PushProjector.ExprCondition` which filters prevent time indicator rex nodes.
