I am currently working on documenting date/time functionality that exists in MonetDB and I have run into some problems/questions. I hope someone can help me out:
1) According to the Temporal Types page (https://www.monetdb.org/ Documentation/SQLreference/Temporal), there should be a type 'daytime'. However, the following fails:
create table t (b daytime); -> type (daytime) unknown in: "create table t (b daytime)" daytime is the mal level type for the sql type time.

Does anyone know whether this feature has been removed or that this is a bug (or that I am perhaps missing something)?
2) Converting strings to dates works like a charm:
SELECT str_to_date('23-09-1987', '%d-%m-%Y'); -> 1987-09-23
But how about converting strings to times/timestamps:
SELECT str_to_date('11:40', '%H:%M'); -> null
I can not seem to find any definitions of built in functions that take a string and produce anything other than a date.
Thanks in advance! Robin
PS: I am running the latest default branch on Ubuntu 14.04.
