Here is the reason: We have a reporting tool that is highly parametric. This tool is an interface to a series of querys stored in a table and we have some difficulties for retrieving date, time and portions of datetime fields in spanish.

So if we do it on UDF functions, we can simply call the function from inside the query and we are going to retrieve de data just as we want it to be in the resultset.
