Julian Hyde commented on CALCITE-2349:
--------------------------------------
You're probably supplying the wrong number of operands. {{<timestamp> -
<interval>}} has two operands. {{<timestamp> - <timestamp> <time unit>}} has
three. Just because you get an error it doesn't mean the bug is in Calcite's
code.
