How to set the linux system time

To make Linux processes run in real-time FIFO scheduling, you need to use the chrt command or sched_setscheduler system call to set the scheduling policy and priority, such as sudochrt-f99./app or configure SCHED_FIFO and priority parameters in the C program, and ensure that the process has CAP_SYS_NICE capability or root permissions, and configure rtprio and memlock restrictions through limits.conf to ensure real-timeness and avoid priority reversal.
