We did a DQA and found out that ODK-X dates are behind with one day. Why is this the case?
The date is NOT one day behind it is saved in a uniform timezone and can be converted to your local timezone.
The standard date format saves the dates in UTC timezone. On the mobile device an other user interfaces the system will convert the date from the UTC timezone to the local timezone. However, if you are looking at the data directly from the database or you created a custom UI you need to use the functions to convert the date correctly.
