Because R1 is synchronizing its time to Google's NTP servers, it automatically becomes an NTP server itseld (stratum level 1 highet that Google's NTP servers). Now other devices can synchronize their time to R1.
NTP uses only the UTC time zone. You must configure the appropriate time zone on each device.
ntp update-calendar - configures the router to update the hardware clock (calendar) with the time learned via NTP.
The hardware clock tracks the date and time on the device even if it restarts, power is lost, etc. When the system is restarted, the hardware clock is used to initialize the software clock.
