Java Convert Facebook created_time to UTC

Question

I am using Facebook graph API to retrieve user wall information. In that, I am getting the post created time value as:

created_time: "2012-04-19T09:00:02+0000"

Can anyone suggest me how to convert this time to UTC or epoch value in Java?

Answer 1

The format of date you receive is ISO 8601.

As described in Converting ISO8601-compliant String to java.util.Date (using Joda-Time):

DateTimeFormatter parser = ISODateTimeFormat.dateTimeNoMillis();
String jtdate = "2012-04-19T09:00:02+0000";
System.out.println(parser.parseDateTime(jtdate));

Answer 2

You basically need to parse the ISO8601 date format. There are libraries out there that would do it for you or you can create your own parser (relatively simply), e.g.
