I can not enter and show current date and time I2c rtc

How do I set the I2C RTC to the current time and date and send it to the Blynk?
I can not enter and show current date and time using a nodemcu

You set/read a physical RTC module with whatever library/sketch method the manufacturer/supplier recommends… and you send that info to your Blynk App with a Blynk.virtualWrite(vPin, value) to a display Widget as you would any data.

do you have any examples using nodemcu with i2c rtc?

Start with something like this if you haven’t already got to this stage https://github.com/sparkfun/SparkFun_DS1307_RTC_Arduino_Library
