> It's helpful when running analytics to be able to do manipulation on dates
> such as extracting month/day/year, converting to th week of year, etc, and
> other formatting as many existing libraries provide. I have a patch going
> through final testing that will add this to the analytcs library.
> One thing I'm sort of amibvialent about is that it exposes that we use Java
> date parsing in the analytics function, because the syntax is the same format
> string that SimpleDateFormat accepts. Ideally there would be an abstraction
> between the analytics language and what's used on the backend to implement
> it. On the other hand, implementing a syntax for time/date formatting is
> something that's been done many many times before, and this is not the only
> place where Java date particulars show through. It would be good to revisit
> this at a later time.
