Hello again!
So taking this step by step, I'm trying to get the time in the serial monitor to make sure that part is correct since everything else will be built on this. This code, when run, displays this in the serial monitor:
09:56:30.035 ->
09:56:30.035 -> C:\Users\bryan\Ap
09:56:30.035 -> al\Temp\.arduinoIDE-unsaved202376-3680-gw8g0r.uhv8s\SetSerial\SetSerial.ino
09:56:30.035 -> Aug 6 2023 09:56:25
09:56:30.035 -> RTC Sync
09:56:30.035 -> 31Dec2095 00:03:53
09:56:31.593 -> ,�� n�>��ɗ�֙��@*����,��8҉����,������8҉
this is the code I'm currently running:

// https://github.com/JChristensen/DS3232RTC
// Copyright (C) 2018 by Jack Christensen and licensed under
// GNU GPL v3.0, https://www.gnu.org/licenses/gpl.html
//
// Example sketch to display the date and time from a DS3231
// or DS3232 RTC every second. Display the temperature once per
// minute. (The DS3231 does a temperature conversion once every
// 64 seconds. This is also the default for the DS3232.)
//
// Set the date and time by entering the following on the Arduino
// serial monitor:
// year,month,day,hour,minute,second,
//
// Where
// year can be two or four digits,
// month is 1-12,
// day is 1-31,
// hour is 0-23, and
// minute and second are 0-59.
//
// Entering the final comma delimiter (after "second") will avoid a
// one-second timeout and will allow the RTC to be set more accurately.
//
// No validity checking is done, invalid values or incomplete syntax
// in the input will result in an incorrect RTC setting.

// but the RTC wants the last two digits of the calendar year.

int y = Serial.parseInt();
if (y >= 100 && y < 1000)

}
}
t = now();
if (t != tLast) {
tLast = t;

if (second(t) == 0) {
float c = myRTC.temperature() / 4.;
float f = c * 9. / 5. + 32.;
Serial << F(" ") << c << F(" C ") << f << F(" F");
}

}

}

}

// followed by a delimiter character to Serial.
// Input value assumed to be between 0 and 99.
void printI00(int val, char delim)
{
if (val < 10) Serial << '0';
Serial << _DEC(val);
if (delim > 0) Serial << delim;
return;
}
I entered the time in the serial monitor message bar according to the parameters laid out in the opening comments (at the time, it was 2023,8,6,09,56,30)
I'm expecting the time code to update every second on the serial monitor. Why am I getting just these initial ones with characters it wont recognize?
