Issue with Connecting Elastic Search

Hi,

We have an issue with connecting Elastic Search with Grafana.
Grafana - version 5.0.4.

The index inside our elastic search has a date stamp like: “requestStart”: “2018-10-31T16:04:42+0200”,

When putting this field in the Time field name while setting up the connection, it shows and error. How can we connect to Grafana ? Any way to connect with this version with timestamp that has UTC field .
