I am trying to execute a block of code when it is past a certain time. However, when the program executes, the current_time variable saves the time the program started, and does not keep time while the program is running.

The only thing I found that could be a possible solution to that problem is putting current_time on a while loop so the time updates while the program is running, but this is shown to crash the program. How to do this while not crashing the program?

import time
import sys

start_time = "07:00:00"
break_time = "10:00:00"
current_time = time.strftime("%H:%M:%S")
while current_time > start_time and current_time < break_time:  
    current_time = time.strftime("%H:%M:%S") # loop crashes the program
    print(current_time)

if current_time < start_time or current_time > break_time:
    print("The program will now be terminated.")
    sys.exit()
