* Do you know what NTP is?

NTP, or Network Time Protocol, synchronizes clocks on computers and devices over networks, aligning them with Coordinated Universal Time (UTC). By ensuring precise timing, NTP keeps devices in sync. That is especially crucial for applications that depend on accurate time, such as financial trading and security protocols.

Here are several reasons why NTP is so important:

Security: Many protocols, including TLS and Kerberos, rely on accurate time to validate certificates and control access. Time mismatches can create security vulnerabilities.
Data Accuracy: Systems like databases need synchronized timestamps to maintain data integrity and accurately track events.
Event Coordination: In distributed systems, synchronized time is crucial for accurate event logs and activity tracking across machines.
Network Efficiency: Many network functions, like timeouts, depend on synchronized time, which helps maintain smooth network performance.

NTP operates over UDP on port 123, which enables fast, efficient time queries across devices, critical to NTP’s functionality.
