puts "Time b:#{b}\n\n"
puts "Time c:#{c}\n\n\n\n"
  
  
# round form  
puts "Time a round form:#{a.round(10)}\n\n"
puts "Time b round form:#{b.round(3)}\n\n"
puts "Time c round form:#{c.round}\n\n"

輸出：

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 round form:2019-01-01 00:00:00 +0100

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

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

範例2：

# Ruby code for Time.round() method 
  
# Ruby code for Time.round() method 
  
# loading library 
require 'time'
  
# declaring time

# 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"
  
  
# round form  
puts "Time a round form:#{a.round(10)}\n\n"
puts "Time b round form:#{b.round(3)}\n\n"
puts "Time c round form:#{c.round}\n\n"

輸出：

Time a:2019-08-28 07:11:47 +0000
