Adding time_zone option to the date range queries

[selimt]

We store our timestamps as UTC in Elasticsearch. When we use the expressions like today or now-1d with the date range queries, we can get incorrect results. Looking at the ES documentation, it looks like there is a way to provide the local timezone:

Would it be possible to add this feature into this package ?
