solarTimeRTC.ino example prints times without zero padding

[drf5n]

The solarTimeRTC example is missing leading zeros on the time elements, and could print ugly times like:

     9:5:1 UTC on Tuesday, April 18, 2023

SolarPosition/examples/solarTimeRTC/solarTimeRTC.ino

Lines 80 to 92 in ba19df4

	Serial.print(someTime.Hour);
	Serial.print(F(":"));
	Serial.print(someTime.Minute);
	Serial.print(F(":"));
	Serial.print(someTime.Second);
	Serial.print(F(" UTC on "));
	Serial.print(dayStr(someTime.Wday));
	Serial.print(F(", "));
	Serial.print(monthStr(someTime.Month));
	Serial.print(F(" "));
	Serial.print(someTime.Day);
	Serial.print(F(", "));
	Serial.println(tmYearToCalendar(someTime.Year));

A few lines like this would solve it:

if(someTime.Second<10)Serial.print('0');

Here's a configured simulation:

Requires some thought about how to handle this.

Here's a solar tracker simulation with text-based 0 padding and steppers:

And without the zero padding on the times:

It isn't that I don't understand the issue. I want to have an overview of all the code before just patching it.

This is just an example and it's up to the programmer to interpret the data.
I am using the library in my solar tracker with no problems so I think discussion of sample code is a waste of time.

I realize it's a nit-picking little thing. Feel free to close with a "won't fix" because the fault lies with Arduino's lack of a Serial.printf("%02d:",0);

I like your library, and am going to use it to build a tracker with steppers like the Wokwi simulation. Thanks.

I'm planning to re-write the example using the JeeLabs/Adafruit RTC library because it has a built in function for formatted text output.
