Fix SQLite time zone reading

[Huliiiiii]

Closes #2319

[Kitt3120]

hey, are you still working on this?

I am currently doing this on my model as a workaround:

impl Model {
    pub fn timestamp_local(
        &self,
    ) -> Result<TimeDateTimeWithTimeZone, time::error::IndeterminateOffset> {
        let ts = self.timestamp;
        Ok(ts.to_offset(UtcOffset::local_offset_at(ts)?))
    }
}

So I am using the normalized timestamps everywhere internally, and when I have to display the actual localized timestamp somewhere, I use timestamp_local().
