Hi,
It's not immediately obvious what the default value of "timezone"
> will be?

The system's locale, like now(); documentation can clarify.
By named parameter, I meant default value. You could construct a timestamp
variable using:
construct_timestamp( year := 1900, hour := 1 )
When I read that code, the first thing I think it should return is:
1900-01-01 01:00:00.0000-07
I agree construct_timestamp( hour := 1 ) and construct_date() are errors:
year is required.

P.S.
I prefer to_timestamp and to_date over the more verbose construct_timestamp.
