Arduino UNO DS1302

On my pc the Arduino ide uses port "COM3" to program a UNO.
A C# program uses the same port.
Button1 writes the pc date/time to the DS1302,
Button2 reads date/time from the DS1302, it is written to label1.
When the port is disconnected, the DS1302 keeps the time with a CR2032 backup battery.
If the port is connected again the proper time can be read by clicking button2 (two times:)

The smallest odd n with a question mark is 45.
The largest left-truncatable prime in base 45 seems to be:
