I have created a employee time sheet and let employee punch in/out by
pressing Ctrl+Shift+;. This works fine but occasionally they punch in wrong
time by manually typing in/out. Now I am using =NOW(), this work better then
Ctrl+Shift+;, only down side is employees have to press F9 to get a current
time. Is there any function that will re-calculate automatically. I am very
new to excel (2007). any comment and suggestion or answer will be greatly
appreciated. Thank you in advance.

You can place a refresh button on the page and assign the following code to it;
Sub ForcedCalculation()
'Assumption - Cell A1 contains the time
Range("A1").Calculate
End Sub

or you can use the following code after adjusting for the range. This code
will refresh everytime anything changes in a cell in the range selected

Private Sub Worksheet_Change(ByVal Target As Range)
Dim MyRange As Range, MyCell As Range
Set MyCell = Target(1, 1)
Set MyRange = [A1:A10] 'define the range here
'
If Intersect(MyCell, MyRange) Is Nothing Then
'you know the cell is not in the range, so exit
Exit Sub
Else
'continue with your cell
With MyCell
'code here
End With
End If
End Sub
