## Proposed changes date_trunc() is a very useful function in Hive, MySQL and Presto. We should add it to Doris. The date_trunc document and some test case is added to this commit, and the implementation code will be supplemented by others. By the way, in my understanding, the registration of functions is involved, so the order of function implementation is BE to FE. I can complete the development of the FE side, but because my C++ is not very good, I hope someone will supplement the implementation of the BE side, and then I will attach the FE side code. ## Types of changes What types of changes does your code introduce to Doris? _Put an `x` in the boxes that apply_ - [ ] Bugfix (non-breaking change which fixes an issue) - [ ] New feature (non-breaking change which adds functionality) - [ ] Breaking change (fix or feature that would cause existing functionality to not work as expected) - [ ] Documentation Update (if none of the other choices apply) - [ ] Code refactor (Modify the code structure, format the code, etc...) - [ ] Optimization.
