The internet keeps track of time using Network Time Protocol (NTP), a system that synchronizes clocks of computers to a few milliseconds of Coordinated Universal Time (UTC). Servers and clients communicate to ensure time synchronization, maintaining accurate timestamps for activities and data consistency across networks. NTP uses a hierarchical system of time sources, with atomic clocks and GPS at the top, ensuring high precision.
