>             Project: Apache NiFi
>          Issue Type: Improvement
>    Affects Versions: 1.2.0, 1.3.0, 1.4.0
>            Reporter: Bryan Bende
>            Priority: Minor
>
> We should support some date related functions in record path. At a minimum I think having a format function like:
> {code}
> format( /someField, 'yyyy-MM-dd', defaultValue)
> {code}
> The main use case for this is using PartitionRecord to partition by month, day, or hour on a date field. 
> Currently you have treat the date as a string and use a sub-string operation to get the part you are interested in, which also assumes the date is in a string form in the first place.
