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)" 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.
