GetTime.ino

/**
 * This example demonstrates how to get the current time using the ArduinoCellular library.
 * It derives the time from GPS connection.
 * 
 * Instructions:
 * 1. Move the Arduino Pro 4G Module to an outdoor location with a clear view of the sky.
 * 2. Provide sufficient power to the Arduino Pro 4G Module. Ideally, use a 5V power supply
 * 3. Upload the sketch to the connected Arduino board.
 * 4. Open the serial monitor to view the output.
