Why exactly does your compile job need to be run at exactly the correct millisecond?
Dear Corona, I need to parse some text files and send the results in more precise or approximate time, 1 second after the data no longer serve because they change constantly.

pthread_barrier_wait
pthread_barrier_wait(3C) Standard C Library Functions pthread_barrier_wait(3C)
NAME
pthread_barrier_wait - synchronize at a barrier
SYNOPSIS
cc -mt [ flag... ] file... [ library... ]
#include <pthread.h>
int pthread_barrier_wait(pthread_barrier_t *barrier);
DESCRIPTION
The pthread_barrier_wait() function synchronizes participating threads at the barrier referenced by barrier. The calling thread blocks
until the required number of threads have called pthread_barrier_wait() specifying the barrier.
When the required number of threads have called pthread_barrier_wait() specifying the barrier, the constant PTHREAD_BARRIER_SERIAL_THREAD
is returned to one unspecified thread and 0 is returned to each of the remaining threads. At this point, the barrier is reset to the state
it had as a result of the most recent pthread_barrier_init(3C) function that referenced it.
The constant PTHREAD_BARRIER_SERIAL_THREAD is defined in <pthread.h> and its value is distinct from any other value returned by
pthread_barrier_wait().
The results are undefined if this function is called with an uninitialized barrier.
If a signal is delivered to a thread blocked on a barrier, upon return from the signal handler the thread resumes waiting at the barrier if
the barrier wait has not completed (that is, if the required number of threads have not arrived at the barrier during the execution of the
signal handler); otherwise, the thread continues as normal from the completed barrier wait. Until the thread in the signal handler returns
from it, it is unspecified whether other threads may proceed past the barrier once they have all reached it.
A thread that has blocked on a barrier does not prevent any unblocked thread that is eligible to use the same processing resources from
eventually making forward progress in its execution.
Eligibility for processing resources is determined by the scheduling policy.
RETURN VALUES
Upon successful completion, the pthread_barrier_wait() function returns PTHREAD_BARRIER_SERIAL_THREAD for a single (arbitrary) thread syn-
chronized at the barrier and 0 for each of the other threads. Otherwise, an error number is returned to indicate the error.
ERRORS
The pthread_barrier_wait() function will fail if:
EINVAL The value specified by barrier does not refer to an initialized barrier object.
