例子 #1 :
# Ruby code for Time.to_i() method
# loading library
require 'time'
# declaring time
a = Time.new(2019)
# declaring time
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"
# to_i form
puts "Time a to_i form : #{a.to_i}\n\n"
puts "Time b to_i form : #{b.to_i}\n\n"
puts "Time c to_i form : #{c.to_i}\n\n"
输出:
Time a : 2019-01-01 00:00:00 +0000
Time b : 2019-10-01 00:00:00 +0000
Time c : 2019-12-31 00:00:00 +0000
Time a to_i form : 1546300800
Time b to_i form : 1569888000
Time c to_i form : 1577750400
例子 #2 :
# Ruby code for Time.to_i() 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"
# to_i form
puts "Time a to_i form : #{a.to_i}\n\n"
puts "Time b to_i form : #{b.to_i}\n\n"
puts "Time c to_i form : #{c.to_i}\n\n"
输出:
Time a : 2019-08-27 12:30:26 +0000
Time b : 1000-10-10 00:00:00 +0000
Time c : 2020-12-01 00:00:00 +0000
Time a to_i form : 1566909026
Time b to_i form : -30585859200
Time c to_i form : 1606780800
