Grafana presumes UTC, you can try with the Dashboard Timezone
But I found a work around, although people will disagree is,
Offset your time with DATEADD(HOUR,-1,Time) AS Time
And Offset your time filter accordingly
Where Time BETWEEN DATEADD( HOUR,+1,$__timeFrom() )
AND DATEADD( HOUR,+1,$__timeTo() )
Takes a bit of messing and then Daylight Savings messes it up again
