ASSISTment 2009 description - chronological ordering

[MrMaks]

📚 Documentation

Hi. In the notebook for analysis of ASSISTment 2009, it is mentioned that order_id column is non-chronological, which is in contradiction to the original website of ASSISTment.

(Source: https://sites.google.com/site/assistmentsdata/how-to-interpret)

Since I see no explicit timestamp column for 2009 dataset, nor have I found any paper explicitly stating it, can you confirm whether the order_id column can be treated as chronological ordering of the time series for each individual user? This ordering matters while creating the time series for actions taken by each user (I did not find code for tripple line formatting of this dataset version anywhere as to confirm whether order_id is in fact correct).
