Ruby Time tv_usec实例讲解

Time＃tv_usec()是一种Time类方法，它返回时间的微秒数。

用法：Time.tv_usec()

参数：时间值

返回：时间的微秒数。

示例1:

# Ruby code for Time.tv_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"
  
  
# tv_usec form  
puts "Time a tv_usec form : #{a.tv_usec}\n\n"
puts "Time b tv_usec form : #{b.tv_usec}\n\n"
puts "Time c tv_usec form : #{c.tv_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 tv_usec form : 0

Time b tv_usec form : 0

Time c tv_usec form : 0

示例2:

# Ruby code for Time.tv_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"
  
  
# tv_usec form  
puts "Time a tv_usec form : #{a.tv_usec}\n\n"
puts "Time b tv_usec form : #{b.tv_usec}\n\n"
puts "Time c tv_usec form : #{c.tv_usec}\n\n"

输出：

Time a : 2019-08-27 09:11:19 +0000

Time b : 1000-10-10 00:00:00 +0000

Time c : 2020-12-01 00:00:00 +0000



Time a tv_usec form : 799402

Time b tv_usec form : 0

Time c tv_usec form : 0
