The scheduling in the Planner is carried out in frames. Thus every start date, duration and end time is stored in frames; according to the European PAL-norm 25 frames take 1 second (1 frame has 25 images, thus 1 frame is 0,04 seconds). For displaying these data in the plan they are converted in the following formats that are required for certain purposes:

• Date specification: 04.05.2011
  Announcement of an event at a certain day 
• Specification to the minute: 04.05.2011 16:25
  Indication of the start time of an event. Here it is mostly rounded up or down to 5 minutes. This time represents the so-called SI-time (SI=Service information) for a time specification that is communicated externally.
• Specification to the second: 04.05.2011 16:25:12
  Specification of the time for a commercial break 
• Specification to the frame: 04.05.2011 16:25:12:21
  for start and end times in the dialogs of slots and events in the Programmer.
