Need to watch the seconds to make sure the clock is running correctly. Furthermore, I tried with the "Clock" code in a standard Module like what you have mentioned but still could not get the result in workbook2 Cell C1 to C1440. If I use same workbook with different sheets, the clock get disturbed and the number will start to run wild.
I would appreciate if you could explain your recommendation/suggestion in a more simpler way as I have almost no knowledge about VBA programmes and not an expert in Excel. Thanks.
