ZingChart: If my server is in UTC +9:30, how should I set the "timezone" attribute ?

So you would want to set timezone attribute to 9.5. This would render a 9 hour and 30 minute difference from UTC 0.

var myConfig = {
    "type": "area", 
    "utc":true,  /* This attribute will ensure your chart reads in UTC time. */ 
    "timezone":9.5, /* This attribute will allow you to set a offset from UTC time */
    ...
};
