NowFunc::new() seeds the timezone with "+00" while the canonical UTC offset remains "+00:00" in ConfigOptions::default().

NowFunc::new(), though deprecated seeds the timezone with "+00" (missing minutes) while the canonical UTC offset remains "+00:00" in ConfigOptions::default().
Existing callers of the deprecated constructor will therefore get a different datatype/ScalarValue than before this change.
