Graph display +2 hour offset

Hello I have a query like this to display data from my sensors on dashboard:

import "timezone"

option location = timezone.location(name: "Europe/Bratislava")

from(bucket: "db")
  |> range(start: 2022-06-11T01:48:00Z, stop: 2022-06-11T03:48:00Z)
  |> filter(fn: (r) => r["_measurement"] == "sens")
  |> filter(fn: (r) => r["device"] == "first_device")
  |> filter(fn: (r) => r["location"] == "sk")
  |> filter(fn: (r) => r["_field"] == "first_device_temperature_1" or r["_field"] == "first_device_temperature_2" or r["_field"] == "first_device_temperature_3" )
  |> aggregateWindow(every: v.windowPeriod, fn: mean, createEmpty: false)
  |> yield(name: "mean")

On dashboard I can see the data (my time is 1:50 and graph display 3:50) +2hour offset (I know that database systems use UTC timezone) but I specify timezone in query and I have still same results.
