TimeUtils

• delay(int milliseconds): performs a delay of a given number of milliseconds (mainly used for synchronization reasons)
• getSeconds(String timeStr): returns the number of seconds corresponding to a time which is in the format [hh:mm:ss]
• compareTimes(String fTimeStr, String sTimeStr): compares two times which are in the format [mm:ss].

WiFiInfo

A tiny class used to encode informations concerning the WiFi networks scan into a well-formed JSON string throughthe toJSONString method. For more details see the HTTP section of the main class of the renderer. In particular look at the getWiFiInfo method.
