Converts a number of hours, minutes and seconds and a corresponding sign value to an equivalent offset value from UTC (Universal Coordinated Time), measured in milliseconds.

sign = (sign >= 0) ? 1 : -1;
hours = (hours >= 0) ? hours : -hours;
minutes = (minutes >= 0) ? minutes : -minutes;
if ((hours > 30) || (minutes > 1800))
    throw new IllegalArgumentException(
            "The magnitude of one or both of the hours or minutes value is outside the acceptable range.");
return sign * (hours * 3600000 + minutes * 60000);
