+
+millis()
+========
+
+Returns the number of milliseconds since the Maple board began running
+the current program. This number will overflow (go back to zero) after
+approximately 50 days.

+.. doxygenfunction:: millis
+
+Example
+-------
+
+The following time prints the value returned by ``millis()`` roughly
+once per second::
+
+    unsigned int time;
+
+    void setup() {
+    }
+
+    void loop() {
+      SerialUSB.print("Time: ");
+      time = millis();
+      // prints time since program started
+      Serial.println(time);
+
+      // wait a second so as not to send massive amounts of data
+      delay(1000);
+    }
+
+Tip
+---
+
+Since the return value for ``millis()`` is an :ref:`unsigned long
+<lang-unsignedlong>`, overflow errors may occur if you try to do math
+with other data types, such as :ref:`ints <lang-int>`.
