红宝石 |日期时间偏移()函数

DateTime#offset()是一个 DateTime 类方法,它返回 DateTime 对象的偏移量。

示例 #1:

# Ruby code for DateTime.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))
  
  
#  offset method
puts "DateTime offset form : #{date_a.offset}\n\n"
  
puts "DateTime offset form : #{date_b.offset}\n\n"
  
puts "DateTime offset form : #{date_c.offset}\n\n"

输出 :

DateTime offset form : 0/1

DateTime offset form : 0/1

DateTime offset form : 1/6

示例 #2:

# Ruby code for DateTime.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')
  
  
#  offset method
puts "DateTime offset form : #{date_a.offset}\n\n"
  
puts "DateTime offset form : #{date_b.offset}\n\n"
  
puts "DateTime offset form : #{date_c.offset}\n\n"

输出 :

DateTime offset form : 0/1

DateTime offset form : 3/16

DateTime offset form : 1/8
