[amibroker] timer to reflect timezone - need help on this code

[idumall]

i'm on Hong Kong time zone and HK has a 12 hours difference to EST. 
i'll like to know how to modify this script to reflect the time zone, 
so that my timer can starts at 9.30pm (HK time) and not 12.00am. many 
thanks.

//

tempnum = Now( 4)-TimeNum() ;


TimeRem = Interval() - ((int(tempnum[BarCount - 1] / 100) * 60) + 
(tempnum[BarCount - 1] - int(tempnum[BarCount - 1] / 100) * 100));
if (TimeRem[BarCount - 1] < 0) TimeRem = 0;
TitleTimeRem = EncodeColor(colorBlueGrey) + "Time Remaining: ";
MinuteVar = int(TimeRem / 60);
SecondsVar = int(frac(TimeRem / 60) * 60);

if (TimeRem[BarCount - 1] > 60)
{
TitleTimeRem = TitleTimeRem + EncodeColor(colorWhite) + MinuteVar 
+ ":" + WriteIf(SecondsVar > 9, "", "0") + SecondsVar;
}
else if (TimeRem[BarCount - 1] > 20)
{
TitleTimeRem = TitleTimeRem + EncodeColor(colorYellow) + MinuteVar 
+ ":" + WriteIf(SecondsVar > 9, "", "0") + SecondsVar;
}
else
{
TitleTimeRem = TitleTimeRem + EncodeColor(colorLime) + MinuteVar 
+ ":" + WriteIf(SecondsVar > 9, "", "0") + SecondsVar;
}

Title =   TitleTimeRem + EncodeColor(colorDarkGreen) ;
