The XML snippet below would pass this check.

<Header>
    <Dt>2018-05-28T10:17:50</Dt>
    <TimeStamp>2018-05-28T12:17:50</TimeStamp>
</Header>

 

The other snippet below however would not pass this check.

<Header>
    <Dt>2018-05-28T08:17:50</Dt>
    <TimeStamp>2018-05-28T12:17:50</TimeStamp>
</Header>
