I am using Grafana 8.3.4 In the Dashboard Settings->Variables, I am using MySQL query as the data source. Even though the values are stored in datetime format in database, it is getting converted to unixtime in variables.

For eg: values in the database - 2022-01-20 05:39:34 Values returned by Grafana - 1642657174000

How to get the values as datetime format?
