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

It seems that in some cases the behavior is very different:

Time.parse("Ends from 28 Jun 2018 12:00 BST").utc.to_s

"2018-06-28 09:00:00 UTC"

Date.parse("Ends from 28 Jun 2018 12:00 BST").to_time.utc.to_s

"2018-06-27 21:00:00 UTC"

DateTime.parse("Ends from 28 Jun 2018 12:00 BST").to_time.utc.to_s

"2018-06-28 11:00:00 UTC"
