/*
   The second version of iSimpleClock. Now, the clocks are displayed via the "label" graphical object. 
   It is possible to change a label color, font size, label location.

   IncGUI_v4.mqh library is required for the indicator operation. 
   IncGUI_v4.mqh library is located here: http://www.mql5.com/en/code/542.
   Direct link for the library download: http://p.mql5.com/data/18/542/IncGUI_v4__4.mqh.
   The library must be located in the MQL5\Include directory of the terminal data folder.
   Terminal data folder can be found the following way: select "Open"
   in the "Journal" tab context menu, and go one level up in the emerged window

   Parameters:

   FontSize - font size;
   FontColor - color;
   Corner - location corner;
   PosX - horizontal offset of the chart margin;
   PosY - vertical offset of the chart margin.
