Difference between DateTime and Time in Ruby

Question

What\'s the difference between DateTime and Time classes in Ruby and what factors would cause me to choose one or the other?

Answer 1

Consider how they handle timezones differently with custom instantiations:

irb(main):001:0> Time.new(2016,9,1)
=> 2016-09-01 00:00:00 -0400
irb(main):002:0> DateTime.new(2016,9,1)
=> Thu, 01 Sep 2016 00:00:00 +0000
irb(main):003:0> Time.new(2016,9,1).to_i
=> 1472702400
irb(main):004:0> DateTime.new(2016,9,1).to_i
=> 1472688000

This can be tricky when creating time ranges, etc.
