Convert GMT date format to only time format - json

Question

I am building an html application using AngularJS wherein I want to display the json file data on html page. Can anyone help me to Convert GMT date format from json file to hour:minutes AM/PM
Json file looks like this:
[
{
"startTime": "Sun May 24 2015 01:00:00 GMT+0530 (IST)",
"endTime": "Sun May 24 2015 01:30:00 GMT+0530 (IST)",
"title": "Event 1"
},
{
"startTime": "Sun May 24 2015 04:00:00 GMT+0530 (IST)",
"endTime": "Sun May 24 2015 06:00:00 GMT+0530 (IST)",
"title": "Event 2"
},
{
"startTime": "Sat May 23 2015 20:00:00 GMT+0530 (IST)",
"endTime": "Sat May 23 2015 21:30:00 GMT+0530 (IST)",
"title": "Event 3"
},
{
"startTime": "Sat May 23 2015 21:30:00 GMT+0530 (IST)",
"endTime": "Sat May 23 2015 22:15:00 GMT+0530 (IST)",
"title": "Event 4"
},
{
"startTime": "Sun May 24 2015 02:00:00 GMT+0530 (IST)",
"endTime": "Sun May 24 2015 03:00:00 GMT+0530 (IST)",
"title": "Event 5"
}
]

Answer 1

assign your json data to a scope variable:
scope.data = [
{
"startTime": "Sun May 24 2015 01:00:00 GMT+0530 (IST)",
"endTime": "Sun May 24 2015 01:30:00 GMT+0530 (IST)",
"title": "Event 1"
},
...
];
in your html, you can use angularjs date filter like this:
<div>{{ data[0] | date: 'h:m a' }}</div>

Answer 2

The link provided by #worldask says
Date to format either as Date object, milliseconds (string or number) or various ISO 8601
datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its shorter
versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If
no timezone is specified in the string input, the time is considered
to be in the local timezone.
So I am using a custom filter for converting Sun May 24 2015 01:00:00 GMT+0530 (IST) to milliseconds and then using angular filter to show as hh:mm AM/PM
HTML
<div ng-repeat="date in dateJson">
{{date.startTime | myDateFilter | date:'hh: mm a' }}
</div>
dateJson is your sample json...
custom filter
app.filter('myDateFilter', function() {
return function(dateString) {
var date = new Date(dateString)
// converting to milliseconds
dateString = date.getTime();
return dateString;
}
});
