22:02 I think you have got a stack buffer overflow there. sprintf writes the formatted string to the buffer plus a 0x00 byte at the end to indicate the end of the string for functions like Serial.println; so there it writes xx/xx/xx 8 bytes + space 1 byte + xx:xx:xx 8 bytes = 17 bytes to the buffer; + 0x00 1 byte past the end of the buffer. We are not noticing any weird effect, because it probably just overwrote the year variable (or another variable ¯\_(ツ)_/¯) in that function with 0, that is not being used after the buffer overflow, and is gone after the function returns. You should have allocated 18 bytes

When I used the I2C scanner it said "No I2C devices found", I made sure my connections are correct, pullup resistors are there, and there are no shortcuts What could be the problem?!
