# Ruby code for DateTime.to_datetime() method
# loading library
require 'date'
# declaring DateTime value
date_a = DateTime.new(2019, 8, 10, 5)
# declaring DateTime value

# declaring DateTime value
date_c = DateTime.new(2019, 8, 10, 4, 10, 9, '+03:00')
# to_datetime method
puts "DateTime to_datetime form : #{date_a.to_datetime}\n\n"
puts "DateTime to_datetime form : #{date_b.to_datetime}\n\n"
puts "DateTime to_datetime form : #{date_c.to_datetime}\n\n"
输出:
DateTime to_datetime form : 2019-08-10T05:00:00+00:00 DateTime to_datetime form : 2018-08-10T04:10:06+04:30 DateTime to_datetime form : 2019-08-10T04:10:09+03:00
