title: Kafka SMT for datetime conversion in ISO UTC datetime format
body: <p>Is it possible to convert a column of type <code>datetime</code> in MySQL be converted to UTC-ISO DateTime format in the source connector?</p>
  
  <p>Input Details<br>
  Column Name: Modified_dtmStamp<br>
  Sample Value: 2018-08-03 16:37:20  </p>
  
  <pre><code>... 
  "transforms.TimestampConverter.type": "org.apache.kafka.connect.transforms.TimestampConverter$Value",
          "transforms.TimestampConverter.field": "Modified_dtmStamp",
          "transforms.TimestampConverter.format": "ISO_INSTANT",
          "transforms.TimestampConverter.target.type": "Timestamp"
  </code></pre>
  
  <p>Implemented the above snippet referring to <a href="https://docs.confluent.io/current/connect/transforms/timestampconverter.html" rel="nofollow noreferrer">https://docs.confluent.io/current/connect/transforms/timestampconverter.html</a>.</p>
  
  <p>Error:</p>
  
  <pre><code>
  "trace": "org.apache.kafka.common.config.ConfigException: Invalid value java.lang.IllegalArgumentException: Illegal pattern character 'I' for configuration TimestampConverter requires a SimpleDateFormat-compatible pattern for string timestamps: ISO_INSTANT\n\tat org.apache.kafka.connect.transforms.TimestampConverter.configure(TimestampConverter.java:263)\n\tat org.apache.kafka.connect.runtime.ConnectorConfig.transformations(ConnectorConfig.java:257)\n\tat ........
  ------------------------------------------------------------------------
  
  </code></pre>
  
  <p>Changing the <code>format</code> to <code>yyyy-MM-dd</code> in the above connector snippet works as given in the examples.</p>
  
  <p>However, looking for UTC-ISO format specifically. ISO_INSTANT does the trick, but not working in this case.</p>
