b = Time.new(2019, 10)
  
# declaring time
c = Time.new(2019, 12, 31)
  
# Time 
puts "Time a : #{a}\n\n"
puts "Time b : #{b}\n\n"
puts "Time c : #{c}\n\n\n\n"
  
  
# utc_offset form 
puts "Time a utc_offset form : #{a.utc_offset}\n\n"
puts "Time b utc_offset form : #{b.utc_offset}\n\n"
puts "Time c utc_offset form : #{c.utc_offset}\n\n"

输出 ：

Time a : 2019-01-01 00:00:00 +0100

Time b : 2019-10-01 00:00:00 +0200

Time c : 2019-12-31 00:00:00 +0100



Time a utc_offset form : 3600

Time b utc_offset form : 7200

Time c utc_offset form : 3600

示例 #2：

# Ruby code for Time.utc_offset() method
  
# loading library
require 'time'
  
# declaring time 
a = Time.now
  
# declaring time
b = Time.new(1000, 10, 10)
  
# declaring time
c = Time.new(2020, 12)
  
# Time 
puts "Time a : #{a}\n\n"
puts "Time b : #{b}\n\n"
puts "Time c : #{c}\n\n\n\n"
  
  
# utc_offset form 
puts "Time a utc_offset form : #{a.utc_offset}\n\n"
puts "Time b utc_offset form : #{b.utc_offset}\n\n"
puts "Time c utc_offset form : #{c.utc_offset}\n\n"

输出 ：
