示例 #1:
# Ruby code for DateTime.new_offset() method
# loading library
require 'date'
# declaring DateTime value
date_a = DateTime.new(2019, 8, 10, 4, 10, 9)
# declaring DateTime value
date_b = DateTime.new(2019, 8, 10.5)
# declaring DateTime value
date_c = DateTime.new(2019, 8, 10, 4, 10, 9, Rational(4, 24))
# new_offset method
puts "DateTime new_offset form : #{date_a.new_offset}\n\n"
puts "DateTime new_offset form : #{date_b.new_offset}\n\n"
puts "DateTime new_offset form : #{date_c.new_offset}\n\n"
输出 :
DateTime new_offset form : 2019-08-10T04:10:09+00:00
DateTime new_offset form : 2019-08-10T12:00:00+00:00
DateTime new_offset form : 2019-08-10T00:10:09+00:00
示例 #2:
# Ruby code for DateTime.new_offset() method
# loading library
require 'date'
# declaring DateTime value
date_a = DateTime.new(2019, 8, 10, 5)
# declaring DateTime value
date_b = DateTime.parse('10 Aug 2018 04:10:06+04:30')
# declaring DateTime value
date_c = DateTime.new(2019, 8, 10, 4, 10, 9, '+03:00')
# new_offset method
puts "DateTime new_offset form : #{date_a.new_offset}\n\n"
puts "DateTime new_offset form : #{date_b.new_offset}\n\n"
puts "DateTime new_offset form : #{date_c.new_offset}\n\n"
