May I know the How Wifi RTC works?
I think this is a poor question but I'm new to this environment.
How many days is the validity of the Wifi RTC Epoch?
Once I received the Epoch I disconnect the internet will it work? Is It give the correct date and time?
I will take a SWAG and say no. The reason is my glasses are not good enough to see what you have so you need to tell us. A schematic, not a frizzy picture would be a big help especially if you include links to each of the hardware devices that show technical information. Azon shows generally just sales info. With the correct hardware you can have it maintain the correct time to within a few PPM for months at a time.

Dear Gilshultz,
Sorry for the inconvenience.
I'm using MKR Wifi 1010 Board. The project name is: ** Serial Monitor Clock**
I have not used any other connections. ONLY MKR WIFI 1010 board.
May I know How an epoch works and What is the validity of an epoch?

The MKR1010 has an external 32KHz crystal and should be pretty accurate in maintaining the time you set from WiFi. You will need to do some experimentation to see how accurate that clock source crystal really is. I'm not familiar with the board, and I don't know if there is active temperature compensation or the ability to modify any settings for best accuracy as there is in an external RTC module like the DS3231.
What time accuracy do you require when not connected to wifi?

Dear cattledog,
Thanks for your responce.
I need an RTC Accuracy, every 5 seconds I need a time.
Sometimes in my location powercuts will happen. So that time Wifi is not available. Initially, Wifi is available after some hours and minutes due to a power cut wifi is not available.
