Does `SimpleDateFormat('yyyy-MM-dd'T'HH:mm:ss'Z'')` Automatically Handle Time Zones?

SimpleDateFormat with "yyyy-MM-dd'T'HH:mm:ss'Z'" Does Not Automatically Set Timezone

The Java SimpleDateFormat constructor:

SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'")

by itself does not set the timezone. Adding a 'Z' to the end of the date/time string merely indicates a GMT/UTC timezone, but does not actually change the underlying date/time value.

To ensure that the parsed date/time is in GMT/UTC, you must explicitly set the timezone.

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'");
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
Date date = sdf.parse("2013-09-29T18:46:19Z");

By setting the timezone to GMT, the parsed date/time will be converted to GMT and displayed correctly.
