我的数组是由

start_date = (Date.today + 10.hours + 30.minutes).to_datetime       
   end_date = (Date.today + 1.day + 18.hours).to_datetime
   period = 0.5/24 
   array = start_date.step(end_date, period).to_a

这是结果（但此结果将涵盖最多62天）

array = 
  [Sat, 25 Feb 2023 10:30:00 +0000, Sat, 25 Feb 2023 11:00:00 +0000, Sat, 25 Feb 2023 11:30:00 +0000,

  Sun, 26 Feb 2023 18:00:00 +0000]

从这个数组中，我想删除从每天的开始到10：29点之间以及从18：00点之后到每天结束之间的所有日期时间。
预期结果：

array = 
  [Sat, 25 Feb 2023 10:30:00 +0000, Sat, 25 Feb 2023 11:00:00 +0000, ....... Sat, 25 Feb 2023 18:00:00 +0000,
  Sun, 26 Feb 2023 10:30:00 +0000, Sun, 26 Feb 2023 11:00:00 +0000, ....... Sun, 26 Feb 2023 18:00:00 +0000]

我试过了

w_start_time = (start_date + 8.hours + 1.minute).strftime('%k:%M:%S')
 w_end_time = (start_date - 1.minute).strftime('%k:%M:%S')
        
 hours = array_of_datestimes.reject! { |n| n.strftime('%k:%M:%S').between?(w_start_time, w_end_time) }

这将返回nil
有人能帮帮我吗？
谢谢

也许你应该试试这个：

array = array.reject { |date| 
  (date.hour < 10 || (date.hour == 10 && date.min < 30)) || 
  (date.hour >= 18) 
}

这对我很有效

w_start_time = (start_date - 1.minute).strftime('%k:%M:%S')
 w_end_time = (start_date + 8.hours - 1.minute).strftime('%k:%M:%S')

 hours = array.filter { |n| n.strftime('%k:%M:%S').between?(w_start_time, w_end_time) }
