范例1:
# Ruby code for Time.to_r() 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_r form
puts "Time a to_r form:#{a.to_r}\n\n"
puts "Time b to_r form:#{b.to_r}\n\n"
puts "Time c to_r form:#{c.to_r}\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 to_r form:1546297200/1 Time b to_r form:1569880800/1 Time c to_r form:1577746800/1
范例2:
# Ruby code for Time.to_r() 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_r form
puts "Time a to_r form:#{a.to_r}\n\n"
puts "Time b to_r form:#{b.to_r}\n\n"
puts "Time c to_r form:#{c.to_r}\n\n"
输出:
Time a:2019-08-27 05:36:10 +0200 Time b:1000-10-10 00:00:00 +0053 Time c:2020-12-01 00:00:00 +0100 Time a to_r form:391719242502690717/250000000 Time b to_r form:-30585862408/1 Time c to_r form:1606777200/1
