Datetime is not a type in SQLite, you are storing date/time
stamps as TEXT here.

Boolean is not a type in SQLite. You are encoding them as
integer, deliberately or by accident. We have no way to know
whether zero is a proper value.

We cannot answer that question without knowing
1- the schema of your database
2- the schema of other peoples database
3- a type-and-data dump of your database
4- a type-and-data dump of other peoples databases
You can generate 3 and 4 yourself with something like
SELECT
typeof(col1 AS t_col1), col1,
typeof(col1 AS t_col2), col2,
...
FROM atable.
I think it is your job to do that comparison, not ours.
If you find anything irregular you can't understand after
consulting
http://www.sqlite.org/datatype3.html and
http://www.sqlite.org/lang_datefunc.html
you can ask that specific question here.
