i.MX 8M Mini - Are clocks synchronized across Cortex A and Cortex M?

I have an i.MX 8M Mini EVK, and I'm running Linux on the Cortex A53 and was planning on running FreeRTOS on the Cortex M4. I was curious, if I'm doing stuff on the Cortex A53, like changing the wall-clock time via Linux (think synchronizing its wall clock to a master clock source), does that change propagate to the Cortex M4 running FreeRTOS? 


If not, how would you reliably synchronize the two clocks to run in step with each other?
