I have the following date: 2011-08-12T20:17:46.384Z. What format is this? I'm trying to parse it with Java 1.4 via DateFormat.getDateInstance().parse(dateStr) and I'm getting
java.text.ParseException: Unparseable date: "2011-08-12T20:17:46.384Z"
I think I should be using SimpleDateFormat for parsing, but I have to know the format string first. All I have for that so far is yyyy-MM-dd, because I don't know what the T means in this string--something time zone-related? This date string is coming from the lcmis:downloadedOn tag shown on Files CMIS download history media type.

The T is just a literal to separate the date from the time, and the Z means “zero hour offset” also known as “Zulu time” (UTC). If your strings always have a “Z” you can use: SimpleDateFormat format = new SimpleDateFormat( “yyyy-MM-dd'T'HH:mm:ss).
The United States is one of the few countries that use “mm-dd-yyyy” as their date format–which is very very unique!
ISO 8601 represents date and time by starting with the year, followed by the month, the day, the hour, the minutes, seconds and milliseconds. For example, 2020-07-10 15:00:00.000, represents the 10th of July 2020 at 3 p.m. (in local time as there is no time zone offset specified—more on that below).
The T is just a literal to separate the date from the time, and the Z means "zero hour offset" also known as "Zulu time" (UTC). If your strings always have a "Z" you can use:
SimpleDateFormat format = new SimpleDateFormat( "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.US); format.setTimeZone(TimeZone.getTimeZone("UTC")); Or using Joda Time, you can use ISODateTimeFormat.dateTime().
