Hello, I am trying to create a countdown clock to indicate when a webcast begins. It starts at 18:00:00 UTC everyday, and I am comparing this time with the current time UTC. This then sets the timer. I have got an algorithm and coded it, but it doesn’t work, and I can’t debug it. Any help appreciated.
I will follow this post with the algorithm.

<script language="javascript" type="text/javascript">
//Calculates Time Remaining Until Next Broadcast
//Defines And Converts Start Time UTC to Seconds
var StartTimeUTC = new Date();
var STHours = StartTimeUTC.setHours(18);
var STMinutes = StartTimeUTC.setMinutes(0);
var STSeconds = StartTimeUTC.setSeconds(0);
var STHoursInSeconds = ((parseInt(STHours) * 60) * 60);
var STMinutesInSeconds = (parseInt(STMinutes) * 60);
var StartSecondsUTC = (parseInt(STHoursInSeconds) + parseInt(STMinutesInSeconds) + parseInt(STSeconds));
//Converts Current UTC to Seconds
var UTCNow = new Date();
var UTHours = UTCNow.getUTCHours;
var UTMinutes = UTCNow.getUTCMinutes;
var UTSeconds = UTCNow.getUTCSeconds;
var UTHoursInSeconds = ((parseInt(UTHours) * 60) * 60);
var UTMinutesInSeconds = (parseInt(UTMinutes) * 60);
var UTCNowSeconds = (parseInt(UTHoursInSeconds) + parseInt(UTMinutesInSeconds) + parseInt(UTSeconds));
//Calculates Time Difference Between Start And Current Time
var SecondsDifference = parseInt(StartSecondsUTC) - parseInt(UTCNowSeconds);
var TimeToGoSeconds;
if (SecondsDifference < 0); //This Resets The Timer Every 24Hrs! (86400 is the number of seconds in a day)
{
TimeToGoSeconds = (86400 + parseInt(SecondsDifference));
}
else
{
TimeToGoSeconds = SecondsDifference;
}
//Re-Converts Time To Go Into HH:MM:SS
var ReturnToTime = new Date()
ReturnToTime.setSeconds(TimeToGoSeconds);
var DisplayHours = ReturnToTime.getHours();
var DisplayMinutes = ReturnToTime.getMinutes();
var DisplaySeconds = ReturnToTime.getSeconds();
if (DisplayHours < 10)
{
DisplayHours = "0" + DisplayHours;
}
if (DisplayMinutes < 10)
{
DisplayMinutes = "0" + DisplayMinutes;
}
if (DisplaySeconds < 10)
{
DisplaySeconds = "0" + DisplaySeconds;
}
var TimeRemainingString = ("Time Until Next Broadcast; " + DisplayHours + ":" + DisplayMinutes + ":" + DisplaySeconds);
