例子 #1 :

# Ruby code for Time.usec() 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"
  
  
# usec form 
puts "Time a usec form : #{a.usec}\n\n"
puts "Time b usec form : #{b.usec}\n\n"
puts "Time c usec form : #{c.usec}\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 usec form : 0

Time b usec form : 0

Time c usec form : 0

例子 #2 :

# Ruby code for Time.usec() 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"
  
  
# usec form 
puts "Time a usec form : #{a.usec}\n\n"
puts "Time b usec form : #{b.usec}\n\n"
puts "Time c usec form : #{c.usec}\n\n"

输出:
