Private Sub Command1_Click()
    Dim milTimes As Variant
    Dim stdTime As Date
    Dim milTime As String
    Dim curMilTime As Variant
    milTime = "2115,0051,1734,0912"
    milTimes = Split(milTime, ",")
    For Each curMilTime In milTimes
        stdTime = militaryToStandardTime(curMilTime)
        Debug.Print curMilTime & " = " & stdTime
End Sub

Private Function militaryToStandardTime(ByVal militaryTime As String) As Date
    Dim n As Date
    Dim curDateTime As String
    Dim strHour As String
    Dim strMinute As String
    Dim ampm As String
    strHour = Left(militaryTime, 2)
    strMinute = Right(militaryTime, 2)
    If Val(strHour) > 12 Then
        strHour = CStr(Val(strHour) - 12)
        ampm = "PM"
        ampm = "AM"
        If strHour = "00" Then
            strHour = "12"
        End If
    End If
    n = Now()
    curDateTime = Day(n) & "/" & Month(n) & "/" & Year(n) & " " & strHour & ":" & strMinute & " " & ampm
    If IsDate(curDateTime) Then
        militaryToStandardTime = CDate(curDateTime)

What was the value of  your?


If it is not in the format of the string that you said that it would be, then the procedure won't work.

Your method would have worked I just tested it wrong. My mistake. I don't know if you can get the points since I already accepted another answer.

The difference betwen our two solutions is that I create a Date out of the military time while, GrahamSkan's method returns a string representing the military time in standard format.

Don't bother to change the points. I just got all the points by mistake on another question. We can't actually do anything with them and anyway, Idle_Mind's solution was far more comprehensive.
