DbFunctions Methods - Please include a FORMAT function for dates

[KingsGithub]

The DbFunctions in EF is useful but unfortunately lacks one thing I see a lot of people need - a way to convert or format date/datetime fields to strings in a specific format - and have that used by the LINQ process in the query itself.
It would be great to be able to use something like dbfunctions.format(someDate[Time], someFormatString) where the formatString makes use of all those pre-defined format pictures, e.g. yyyyMM or yyyy.mm.dd or YYYY.MM.DD HH:MI:SS or whatever.
Right now it's just ridiculously hard - unless of course there's a straight-forward and simple way that I'm just not familiar with????
Please.
