Osweb JATOS results have dates with one month difference
One of our researchers noticed that there was a discrepancy in the dates recorded in their results file.
All of the date_* columns have values that are one month off (earlier) than the datetime (which is the correct date). E.g. for datetime: "Thu Sep 07 2023 22:16:28 GMT+0200 (Central European Summer Time)", the date_startdate column in the converted file would say 07-08-23. This occurred for all dates present (and for all months) in the file.
In the unconverted file, I found similar values under "startdate" (without the "date_" part). So I'm guessing it's not a conversion problem. But that leaves me wondering what went wrong. As this is data from many participants, I guess the problem can't really be on their end.
For context, the versioning was:
- OSWeb version of the task was: 1.4.11
- Jatos: 3.7.3
- Converted with version 18.104.22.168
