I think you want to offset the time, I think the Graphs are forced to UTC even when not selected, and Grafana always expects UTC
I noticed this with trying to view the last Hour of data when i knew data was in the DB but Grafana shows nothing
I found this solution, Select Local browser Timezone, Shift your time data by UTC and shift the Time Filter by UTC offset the other direction
This is for MS SQL so I’m sorry if it’s no use
========================
DECLARE @offset INT = DATEDIFF(hour, GETDATE(), GETUTCDATE())
SELECT dateadd(hour, @offset, [TestExecutedAt]) as ‘time’
…
…
…
WHERE [TestExecutedAt] Between dateadd(hour, -@offset, $__timeFrom())
AND dateadd(hour, -@offset, $__timeTo())
=============================
