def #{column_type}(*args, **options)
  args.each { |name| column(name, :#{column_type}, options) }
end

[4] pry(#<CreateUser>)> $ t.timestamps

def timestamps(**options)
  options[:null] = false if options[:null].nil?

  column(:created_at, :datetime, options)
  column(:updated_at, :datetime, options)
end

correct use case singular "timestamp"

t.timestamp :occured_at
