Here is a sample of writing a log file.

Private Sub WriteLog()
' trap error in case network not available
On Error GoTo trap
Dim log As String ' for the text to send to the log file
Dim ff As Long ' for the link to the text file
ff = FreeFile ' get a free file chammel
' create the text for the log
log = Format(Date, "ddd dd-mmm-yyyy") & " BookX opened as "
If ThisWorkbook.ReadOnly Then
log = log & "Read Only."
Else
log = log & "Read Write."
End If
' open the file for append
'note: if the file doesn't exist then it will be created automatically
Open "X:\LogFolder\THISBOOK_LOG.TXT" For Append As ff
' send the text to the log file
Print #ff, log
' then close it
Close #ff


trap: Err.Clear


End Sub

You should be able to modify it to write on opening, write on closing.

Use the Workbook.Open event and the Workbook_BeforeClose event.
You can get the user login name with

uname = CreateObject("Wscript.Network").UserName

or

Public Declare Function GetUserName Lib "advapi32.dll" _
Alias "GetUserNameA" _
(ByVal lpBuffer As String, _
nSize As Long) As Long

Public Function UserName() As String
Dim sName As String * 256
Dim cChars As Long
cChars = 256
If GetUserName(sName, cChars) Then
UserName = Left(sName, cChars - 1)
End If
End Function
