Calculating hours/minutes between time ranges

[excelforeverything]

Hello all,

I'm in dire need of finding a better solution to this problem:

I am in need of caclulating the time between multiple time ranges. Time Range A is a recurring schedule for the month of November, that allocates specific time slots to users, who are then allowed to login during these specific times slots. If the user happens to login outside of these time slots, goes over their allotted time slot or logins in before their allotted times slots then I need to calculate the hours/minutes that they are logged in anywhere outside of their assigned time slot. I am given a large log of the date and duration that users have logged in, which we will call Time Range B.

***Happy to upload excel file if necessary.

Example of Time Range A/Recurring Schedule:

User Name	Start time	End time
User 1	20:54	23:59
User 1	0:00	6:45
User 1​	9:32	11:45
User 1​	19:38	21:35
User 2	6:25	10:00

Example of Time Range B/User Log of Date/Duration:

User Name Start Time Start Date End Time End Date Duration User 1 19:55:14 11/02/18 20:57:02 11/02/18 01:01:48 User 1​ 8:41:40 11/03/18 11:56:10 11/03/18 03:14:30 User 1​ 11:44:16 11/04/18 11:52:24 11/04/18 00:08:08 User 1​ 11:57:18 11/04/18 12:50:40 11/04/18 00:53:22 User 1​ 11:07:00 11/05/18 12:06:02 11/05/18 00:59:02 <colgroup><col><col><col><col><col><col></colgroup><tbody> </tbody> <strike></strike> User 2​ 17:55:37 11/20/18 18:05:17 11/20/18 00:09:40 User 2​ 11:50:54 11/21/18 13:36:32 11/21/18 01:45:38 User 2​ 14:42:20 11/21/18 16:02:36 11/21/18 01:20:16 User 2​ 5:34:22 11/23/18 6:49:00 11/23/18 01:14:38 User 2​ 6:17:01 11/23/18 6:47:14 11/23/18 00:30:13 User 2​ 5:52:44 11/24/18 7:25:38 11/24/18 01:32:54 <colgroup><col><col><col><col><col><col></colgroup><tbody> </tbody> <strike></strike> <colgroup><col><col><col><col><col><col></colgroup><tbody> </tbody> <strike></strike>
