Time#-() 是一個 Time 類方法,它在減去秒後返回一個新的時間值。
用法:Time.-()
參數:時間值
Return: 減去秒後的新時間值。
示例#1:
# Ruby code for Time.-() 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"
# - form
puts "Time a - form : #{a - 1200}\n\n"
puts "Time b - form : #{b - (60 * 60 * 24)}\n\n"
puts "Time c - form : #{c - (100)}\n\n"
輸出:
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 - form : 2018-12-31 23:40:00 +0000 Time b - form : 2019-09-30 00:00:00 +0000 Time c - form : 2019-12-30 23:58:20 +0000
代碼 #2:-() 方法示例
# Ruby code for Time.-() 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"
# - form
puts "Time a - form : #{a - 1200}\n\n"
puts "Time b - form : #{b - (60 * 60 * 24)}\n\n"
puts "Time c - form : #{c - (100)}\n\n"
輸出:
Time a : 2019-08-27 11:20:57 +0000 Time b : 1000-10-10 00:00:00 +0000 Time c : 2020-12-01 00:00:00 +0000 Time a - form : 2019-08-27 11:00:57 +0000 Time b - form : 1000-10-09 00:00:00 +0000 Time c - form : 2020-11-30 23:58:20 +0000
