Re: Syntax of TIMESTAMP [WITHOUT TIME ZONE], TIMESTAMP WITH LOCAL TIME ZONE and TIMESTAMP WITH TIME ZONE in Calcite 1.17


Thanks Julian.

Seems like Oracle's syntax supports:

TIMESTAMP '1997-01-31 09:26:56.66 +02:00'

TIMESTAMP '1999-01-15 8:00:00 US/Pacific'

TIMESTAMP '1997-01-31 09:26:50.12'

However, all these syntax failed with parser exception: not in format
'yyyy-MM-dd HH:mm:ss'

Also, based on Oracle examples, Calcite doc[1] is not really out of date.
