I want to convert Date from "YYYY-MM-DD" to "YYYY-MM-DDThh:mm:ss-hh:mm" format in Apex. Ex. "2016-05-20" should be converted to "2016-05-20T00:00:00-00:00". Any help/suggestion is appreciated.

 I tried the "yyyy-MM-dd'T'HH:mm:ss.SSSXXX" pattern and I am able to convert Date from "YYYY-MM-DD" to "YYYY-MM-DDThh:mm:ss-hh:mm" format as given below-

    Date d =; Datetime myDT = datetime.newInstance(d.year(), d.month(),; String myDate = myDT.format('yyyy-MM-dd'T'HH:mm:ss.SSSXXX');

  "YYYY-MM-DDThh:mm:ss-hh:mm" is ISO 8601

  format. Check this link- for ISO formats.
