The records are ordered by the starttime of the lesson. This is usually in intervals of 30 of 60 minutes.
The attributes date0, pronr0, proname0 and duration0 belong together. This was there are always 5 columns that can be shown. 

Have a look at this section:
"time": 810, "date0": "20120928", "pronr0": 175864, "proname0": "Stef  Gresel", "duration0": 150,
It means that on 810 (13:30) on september 28th, Stef Gresel has an available spot in his agenda for max. 150 minutes. This available spot is to be shown in the first column.

Now look at this section in the same record:
"date4": "20121001", "pronr4": 51264, "proname4": "Barbara van Strien", “duration4": 150
Since it is in the same record, the start time is still 810 (13:30). It means that Barbara van Strien has an available slot in her agenda on October 1st for max. 150 minutes. This slot should be shown in the 5th column.

If you look 1 record before this at the time 780 (13:00) you see this section:
"date4": "20121001", "pronr4": 51264, "proname4": "Barbara van Strien", "duration4": 180
Apparently Barbara was already available 30 minutes earlier. And if you would book your lesson in this slot the max. duration of you lesson could be 180 minutes. Of course you’d only be able to book a lesson of 180 minutes if there would be a lessontype available in the /igg/lessontypes resultset that lasts for 180 minutes, which is unlikely.
