Obtaining Current Moment in ISO 8601 Format with Date, Hour, and Minute

The query pertains to retrieving the current moment in ISO 8601 format, which follows the structure of "2010-10-12T08:50Z." This format represents a specific moment in time, including the date, hour, minute, and UTC offset.

To achieve this, the preferred approach utilizes the SimpleDateFormat class, which allows for the formatting of any Date object. By specifying a specific format string, you can control the output format.

TimeZone tz = TimeZone.getTimeZone("UTC");
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm'Z'"); // Quoted "Z" to indicate UTC, no timezone offset
df.setTimeZone(tz);
String nowAsISO = df.format(new Date());

In the code, note the following:

• TimeZone tz: Represents the UTC timezone.
• DateFormat df: An instance of SimpleDateFormat configured to format a Date object using the specified format string.
• df.setTimeZone(tz): Sets the timezone for the formatter to UTC.
• nowAsISO: Contains the current time in ISO 8601 format as a string.
