I have the if statement that I need help with.
What I am trying to do is check inside xml document in objXMLInputDoc to see if the NewWarrantStatus/WarrantStatusTime is less than current time.

In my if statement I put < 4 which is I think should be 4 minutes... but am not sure if that's correct.

How do I do this?
objXMLInputDoc has the following xml

Code:
<?xml version="1.0" encoding="UTF-8"?>
<UpdateWarrantStatus>
    <WarrantNumber>
        <ID>2</ID>
    </WarrantNumber>
    <CurrentWarrantStatus>
        <WarrantStatusTypeText code="RECALLED">Recalled Inactive</WarrantStatusTypeText>
        <WarrantStatusDate>2018-10-16</WarrantStatusDate>
    </CurrentWarrantStatus>
    <NewWarrantStatus>
        <WarrantStatusTypeText code="IBARCLR">Warrant Cleared by Arrest</WarrantStatusTypeText>
        <WarrantStatusDate>2018-10-17</WarrantStatusDate>
        <WarrantStatusTime>12:10:00</WarrantStatusTime>
        <WarrantStatusComment>New status</WarrantStatusComment>
    </NewWarrantStatus>
</UpdateWarrantStatus>
What I have tried
Code:
dtmNewWarrantStatusDateTime = CDate(objXMLInputDoc.DocumentElement.SelectSingleNode("msc:NewWarrantStatus/msc:WarrantStatusDate", objXMLNameSpaceManager).InnerText + " " + objXMLInputDoc.DocumentElement.SelectSingleNode("msc:NewWarrantStatus/msc:WarrantStatusTime", objXMLNameSpaceManager).InnerText)
        'I am using < 4 thinking this can be 4 minutes earlier than current time but it is not working
        If ((dtmNewWarrantStatusDateTime.Date = Date.Today) And (DateDiff(DateInterval.Minute, Date.Now, dtmNewWarrantStatusDateTime) < 1)) Then
        Else
            strErrorResponse = "A Warrant Status Date and Time combination is invalid because time is in the future. i.e more than 4 minutes."
            objXMLInputDoc.DocumentElement.SetAttribute("error", strErrorResponse)
        End If
