To do this however, the attribute "<InputDateFormat>" MUST be empty.

E.g

<sxi:DateConverter InputDateFormat="" OutputDateFormat="dd-MM-yyyy"/>

Example:

Date= “15/03/2019”

The above "Date" is in a dd/MM/yyyy format, we want to change the format to yyyy-MM-dd.

<sxi:Field name="//*[local-name()=’Date’]">
 <sxi:Rules>
    <sxi:DateConverter InputDateFormat="dd/MM/yyyy" OutputDateFormat="yyyy-MM-dd"/>
 </sxi:Rules>
 <sxi:OutputField>Date</sxi:OutputField>
</sxi:Field>

After using the above config "Date" will look as follows:

Date = "2019-03-15"

You can also use "DateConverter" for time.
