The Netbell product comes with a built-in real time clock with NTP automatic Internet time setting and gets its time from a standard internet NTP time server. It looks for time every 30 minutes from NTP server by default (users changeable), which maintains the time between requests with a Real Time Clock (RTC) within the main CPU.
