   ## Rationale for this change
   @mhilton's change to `date_trunc` to make it correct also potentially slows 
it down
   
   Let's try and recover the performance (and then some) so DataFusion 51 can 
be both more correct **and** faster
   
   ## What changes are included in this PR?
   
   Use `try_unary_op` methods to avoid allocating intermediate arrays to 
improve performance
   
   ## Are these changes tested?
   
   functionally by CI
   
   I will run benchmarks on this PR as well
