PowerBi PowerQuery - Convert Unix Timestamp to DateTime

The Unix timestamp represents the number of seconds since 1970-01-01. So to convert it to a DateTime in PowerQuery, use the following code:

 = Table.AddColumn(Source, "unixTimeStamp to DateTime", each #datetimezone(1970,1,1,0,0,0,0,0) + #duration(0,0,0,[unixtimestamp]))
