UPDATE posts SET start_date='2016-02-24 16:00:00.000 +00:00' WHERE id = 123;
sequelize@3.4.0 (expected)
{ startDate: Thu Feb 25 2016 00:00:00 GMT+0800 (CST) }
sequelize@3.19.3 (wrong format)
{ startDate: '2016-02-24 16:00:00.000 +00:00' }
No problem when execute INSERT, both return local datetime (i.e. CST) .
