title: Kusto Query to extract mmm-yyyy from timestamp column
body: <p>I have a timestamp column with datetime values. I want to extract year-month from it. 
  For Example: if timestamp is 2020-02-19T13:42:51.393Z, output I want is Feb-2020. </p>
  
  <p>I tried looking at <a href="https://docs.microsoft.com/en-us/azure/data-explorer/kusto/query/format-datetimefunction" rel="nofollow noreferrer">https://docs.microsoft.com/en-us/azure/data-explorer/kusto/query/format-datetimefunction</a>, it has nothing for month. </p>
  
  <p>Thanks in advance. </p>
