Timeslot

  A timeslot is the unit of time in the Day view.  You can set
  timeslots to 5, 15, 30, or 60 minutes.  You can also select
  multiple timeslots and join them to create entries that last
  longer than the default timeslot.

  You can set finer intervals of time for entries (down to 1
  minute) with the resize bar.  By default, the resize bar uses
  an interval of 5 minutes, but you can modify it in the Day
  view dialog box.
