how to place time to stop the job?

hi,
I have this line of code:

schedule.every().tuesday.at("01:48").do(run_threaded, job4) #follow followers

and I have to stop this job after some exact time, as the job could crash and will not work good in next day, help me please to fix this line:

schedule.cancel_job.every().tuesday.at("01:50").do(run_threaded, job4) #follow followers

Start by reviewing the scheduling and job-cancellation APIs used by the two expressions in the issue. Confirm whether the requested behavior is supported and define what should happen when the job reaches the stated stop time, including the crash case; completion should be demonstrated with a documented example or test.
