Wrongly transformed timestamp while using elasticsearch as datasource

I am using Elasticsearch as datasource in Grafana and I have created simple table containing raw data in one of my dashboards. All dates are in UTC timezone. When table view button is “on” I can see such data:

But when I select UTC timezone in time range options.
And switch table view to “off” field timestamp changes unexpectedly:

For some reason it substracts 2 hours from it but do not have an effect on other fields. I was expecting it not to have any influence on those dates as they are already in UTC timezone.

How does Grafana recognizes timezones assigned to specified dates?
