Fix SQL Create Bugs

[dakkad]

The SQL create statement has some bugs in it's data type definition.

I agree, the create statement in the python does have some bugs, at the time I wasn't aware of how SQLite uses dynamic typing and was able to cope regardless of the mistakes (which I learned from following some example code online at the time). I've applied what I've learned subsequently to the create statement in the Android codebase. I'd prefer SQLlite to support date & time explicitly and unambiguously, however it seems it can coerce the incoming time/date fields into three file types. A good working example is http://www.sqlitetutorial.net/sqlite-date/

Additional references/sources include the following for SQLlite:

and the following for SQL generally

Thanks for the observation. I'll update the python code shortly.
