I want to remove duplicates on Time, User ID, and To Location. My data set for time though comes down to the second. I want to remove duplicates that occur within the same hour even if the hour flips over. A scan at 8:30 and another at 9:10 recognized as duplicates. I'm not sure how to go about writing the formula into a helper column or adding to the VBA (VBA Preferred).

VBA Code: 
Sub Remove()
On Error GoTo Error
    Application.ScreenUpdating = False
    Sheets("Data").Unprotect Password:=""
    With Sheets("Data")
    With .Range("A2", .Range("F" & Rows.Count).End(xlUp))
      .Columns(5).Value = .Worksheet.Evaluate(Replace("if(mid(#,2,3)=""TRN"",#&""||""&ROW(#),#)", "#", .Columns(5).Address))
      .Columns(5).Value = .Worksheet.Evaluate(Replace("if(mid(#,2,3)=""EVN"",#&""||""&ROW(#),#)", "#", .Columns(5).Address))
      .RemoveDuplicates Columns:=Array(2, 5), Header:=xlNo
      .Columns(5).Replace What:="||*", Replacement:="", LookAt:=xlPart

''''below is where I want to do the within an hour check on column 1

      .RemoveDuplicates Columns:=Array(1, 2, 5), Header:=xlNo
    End With
    End With
    ActiveWorkbook.Worksheets("Data").Activate
    Application.ScreenUpdating = True
    MsgBox "Duplicates Removed."
    Exit Sub
   
Error:
    Application.ScreenUpdating = True
    MsgBox "Something went wrong; clear, paste, and try again."
End Sub

What if 3 'duplicates' occurred at 8:30, 9:10 and 10:00?
The first 2 are within an hour of each other, the last 2 are within an hour of each other but first and last are not within an hour of each other.
This scenario happens with your user133 so are your yellow rows indicating that they all do get deleted even though fist & last are not within an hour?

3 duplicates spaced as described I would still like consolidated to 1, my data set should not ever span more than that. This rarely happens, I'm mainly trying to avoid counting something moved early morning and later in the afternoon as one.

I noticed user133 after the fact please ignore the first highlighted one.

Let's start there. Here is something to consider as a possible starting point if Remove duplicates was then just used on col G.

However that would not achieve your desired 'remove duplicates' outcome if it was possible that the same user ID could also have a separate 'within an hour' duplicate group like this. Is this scenario possible with your data?

This is most definitely a scenario. The "To Location" may even be the same.

Hmm, the "To Location" repeat was looming as my next question.

This seems to be one way and then use column G only as the remove duplicates criterion.
