I want the user time running continuously 24hrs even he's not online

I need help on how to setup the user time limit on my mikrotik haplite rb941-2nd, I want to set the time limit of the user for 24 hrs only. Meaning the time will start running after he logged in and its still continuously running even if he is not using logged in or using the internet. Just limit for 24 hrs. Because in my current setup, if the user will not use the internet the time will stop and can be consumed in another day. I want that the remaining time will not be used after 24 hrs. Thank you hope you can help me with this.

Seems to me that you are talking about a hotspot setup. If yes, increase the session time to 24H
If not, please post more details
