Why Time read error data than MSSQL?

Use the MSSQL function like:

select Calcine_time as time,xbar
from [Multi_get_Rbar_sng](format(dateadd(DD,-7,getdate()),'yyyy-MM-dd'), format(getdate(),'yyyy-MM-dd'),'XXXXXXX','XXXXXXX') 

the Microsoft Sql Management get is (2020-03-31 11:26:59)

why Grafana get 's more then Eight hours (2020-03-31 19:26:59)

The default is use your browser’s time zone. It can be defined per dashboard in the dashboard settings. The other option is UTC.

For Grafana 7.0, there will be more support for different time zones.

It’s OK.Thank you for your reply.
