A network technician observes that several devices on the network are not maintaining accurate system clocks, leading to authentication errors with certain time-sensitive services. Assuming the appropriate configuration on the devices for time updates, what should be the BEST next step in troubleshooting the observed discrepancy in system time?
Deploy the latest software updates to all devices to correct potential time-keeping bugs.
Inspect the system time on the central server tasked with clock updates and confirm its network accessibility.
Reinitialize the service responsible for time updates on devices showing the wrong time.
Examine the network for address duplications that could be resulting in connectivity issues.
