/*
 * Time
 *
 * This sketch demonstrates how to retrieve the Iridium system time
 * from the modem using the getSystemTime method. This uses
 * the Iridium command AT-MSSTM to acquire the time.  The method will
 * fail if the Iridium network has not yet been acquired.
 *
 * Assumptions
 *
 * The sketch assumes an Arduino Mega or other Arduino-like device with
 * multiple HardwareSerial ports. It assumes the satellite modem is
 * connected to Serial1. Change this as needed. SoftwareSerial on an Uno
 * works fine as well.
