title: Arduino IDE doesn't find sys/time.h in Windows
body: <p>I'm trying to follow <a href="https://azure.microsoft.com/en-us/resources/samples/iot-hub-c-m0wifi-getstartedkit/" rel="nofollow noreferrer">this tutorial</a> to start testing my new Adafruit Azure IoT starter Kit that comes with an Arduino Feather M0 Wifi. I was able to setup the Arduino IDE 1.8.4 (From Windows Store) on my PC which is a Windows 10. In the step 1.8 (Build Your Remote Monitoring Sample), when I try to compile the solution "remote_monitoring.ino" dowonload from <a href="https://github.com/Azure-Samples/iot-hub-c-m0wifi-getstartedkit/archive/master.zip" rel="nofollow noreferrer">here</a>, it appears the following error:</p>
  
  <blockquote>
    <p>C:\iot-hub-c-m0wifi-getstartedkit-master\remote_monitoring\remote_monitoring.ino:12:22:
    fatal error: sys/time.h: No such file or directory</p>
    
    <p><code>#include &lt;sys/time.h&gt;</code></p>
    
    <p>compilation terminated.</p>
    
    <p>exit status 1 Error compiling for board Arduino/Genuino Uno.</p>
  </blockquote>
  
  <p>It seems like in Windows, including sys/time.h just doesn't Works, but if I try to delete the sys/ part, it comes the following error:</p>
  
  <blockquote>
    <p>C:\Users\jonguz\OneDrive -

    fatal error: cstdlib: No such file or directory</p>
    
    <p><code>#include &lt;cstdlib&gt;</code></p>
  </blockquote>
  
  <p>I appreciate your help.</p>
