Datetime conversion in Mysql and javascript -

i using javascript , mysql store datetime

     var twodigits = function (d) {          if (0 <= d && d < 10) return "0" + d.tostring();          if (-10 < d && d < 0) return "-0" + (-1 * d).tostring();          return d.tostring();      };        date.prototype.tomysqlformat = function () {          return this.getutcfullyear() + "-" + twodigits(1 + this.getutcmonth()) + "-" + twodigits(this.getutcdate()) + " " + twodigits(this.getutchours()) + ":" + twodigits(this.getutcminutes()) + ":" + twodigits(this.getutcseconds());      };

so when send "2015-07-11 10:00:00" stores "2015-07-11 04:30:00" in db

var p = new date("2015-07-11 10:00:00").tomysqlformat (); 

when retrieve value db "2015-07-10t23:00:00.000z".

using var x = new date("2015-07-10t23:00:00.000z"), gives me   sat jul 11 2015 04:30:00 gmt+0530 (india standard time) 

gmt here coming wrong. utc time receiving. time zone +0530

try adding below in "my.cnf" file zone u need

default_time_zone='+05:30' or '+00:00' 

or

timezone='utc' or 'gmt'
