参数。时间值
返回:这个时间对象的哈希代码。
例子 #1 :
# Ruby code for Time.hash() method
# 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"
# hash form
puts "Time a hash form : #{a.hash}\n\n"
puts "Time b hash form : #{b.hash}\n\n"
puts "Time c hash form : #{c.hash}\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 hash form : 4330006450553416724
Time b hash form : 3038503388982473327
Time c hash form : 2435094560190234940
例子 #2 :
# Ruby code for Time.hash() method
# 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"
# hash form
puts "Time a hash form : #{a.hash}\n\n"
puts "Time b hash form : #{b.hash}\n\n"
puts "Time c hash form : #{c.hash}\n\n"
输出:
Time a : 2019-08-27 03:37:11 +0200
Time b : 1000-10-10 00:00:00 +0053
Time c : 2020-12-01 00:00:00 +0100
Time a hash form : -12417875111583895
Time b hash form : 1057726050809129009
Time c hash form : 3133502209693339851
