Rails date properties won't save to MySQL database - mysql

Question

I have a rails application which is running MySQL in production and SQLite in development. In development mode everything is working fine, but in production datetime properties just won't get saved to the database (even the created_at and updated_at won't). The field is not null, but 0000-00-00 00:00:00. How is this possible? I did some research but I can't fix it.
schema.rb:
# encoding: UTF-8
# This file is auto-generated from the current state of the database. Instead
# of editing this file, please use the migrations feature of Active Record to
# incrementally modify your database, and then regenerate this schema definition.
#
# Note that this schema.rb definition is the authoritative source for your
# database schema. If you need to create the application database on another
# system, you should be using db:schema:load, not running all the migrations
# from scratch. The latter is a flawed and unsustainable approach (the more migrations
# you'll amass, the slower it'll run and the greater likelihood for issues).
#
# It's strongly recommended to check this file into your version control system.
