Jark Wu commented on CALCITE-1912:
----------------------------------

Hi [~julianhyde] do you have suggestions/reference about how to implement this 
?  Especially, the "temporal table in one of the standard data sets". Do we 
need to introduce a new interface `TemporalTable` which extends 
`org.apache.calcite.schema.impl.Table` ? 

> Support "FOR SYSTEM_TIME AS OF" in regular queries
