//    This Version requires Allow DLL Imports be set in Common Tab when you add this to a chart.
//    You can also enable this by default in the Options>Expert Advisors Tab, but you may want
//    to turn off "Confirm DLL Function Calls"
//
//    ShowLocal - Set to tru to show your local time zone
//    corner    - 0 = top left, 1 = top right, 2 = bottom left, 3 = bottom right
//    topOff    - pixels from top to show the clock
//    labelColor- Color of label
//    clockColor- Color of clock
//    show12HourTime - true show 12 hour time, false, show 24 hour time
