Hi Fabien, 
you can actually use skiplist indices with ISO date strings. 
You can even use them to do range queries with 

  FILTER x.date < '2016.10' AND x.date > '2015.10.31'

( see 
https://docs.arangodb.com/2.8/Aql/DateFunctions.html#working-with-dates-and-indices
 
for more details)

so velocypack will not bring you any functional advantage above the current 
possibilitieies.

In general, 3.0 won't support working with the velocypack date type yet; 
starting from the missing possibility to send it in from your application, 
continuing to missing support for it in AQL.

We will work on implementing the support for the enhanced velocypack data 
types during the 3.x release cycle.

Cheers, 
Willi
