The pattern in your post would give you 8 time periods in a standard workday
or 24 time periods in a civil day, not 10. But if you mean you need to see
the hours of the day in the timescale, simply right mouse click on the
timeline and change the units, perhaps adding a 3rd tier so you'd have it
like Weeks, Days, Hours or Months, Days, Hours - whatever works for you.
You might also want to go to the Tools, Options, menu, View tab and select a
date format that includes a time component as well.
