SQLite has no DATETIME datatype. This is just a string.

This compares two strings.

Something like this is needed, but you need to use a string containing a date
value in a supported format:
$ sqlite3
sqlite> select '2015-01-02 13:46:23.818-0800' < datetime('2015-01-02 20:47:18');
1
sqlite> select datetime('2015-01-02 13:46:23.818-0800') < datetime('2015-01-02
20:47:18');
sqlite> select datetime('2015-01-02 13:46:23.818-08:00') < datetime('2015-01-02
20:47:18');
