NTP Time
Network Time Protocol  WIKI
Here you can set the server from which your gadget gets the accurate Coordinated Universal Time (GMT0). For example: pool.ntp.org Only works in Client mode with internet access.

Time Zone
Simply select the city, no other action required. It automatically handles daylight saving time according to the region's schedule. It knows when the sun rises and sets in local time, requires GPS coordinates with two decimal places.

Date Format
The %DATE will be displayed in this format.

Set Time
Sets the internal clock according to the date and time taken from the browser, corresponding to the selected time zone here. If an external RTC module is connected, it also sets that. The time zone is saved only with a complete Setup save.

Stratum 2
If checked, the module acts as an NTP server. The time zone must be GMT0. In the Setup/Communication menu, the UDP INCOMING PORT value is 123. If this function is used, the module cannot receive anything on the UDP channel. UDP sending still works. The use of an external RTC module DS3231 is recommended, with an accuracy of +-1 minute per year.
The following command, written in the Windows command prompt with the module's IP address, tests the NTP server:
w32tm /stripchart /samples:10 /computer:192.168.0.88
