Loading dates in ISO format​

You can use ISO date format in Gantt. For this, you need to redefine functions that parse and serialize dates in Gantt:

gantt.templates.parse_date = function(date) { 
    return new Date(date);
};
gantt.templates.format_date = function(date) { 
    return date.toISOString();
};

Changing the date format dynamically​

If you need to change the date format dynamically, it is necessary to modify the parse_date template in the following way:

var cfg = gantt.config;
var strToDate = gantt.date.str_to_date(cfg.date_format, cfg.server_utc);

gantt.templates.parse_date = function(date){
    return strToDate (date);
};
