Hi,
I have a Date object, and I need to obtain it in a human readable format.
If I use date.toString(), it gives:
Fri Jan 26 17:47:57 CET 2007

What can I do to obtain it in the
07-01-26 17:47
format?

Thanks.

My program does this everyday. What I did was:

    String timeString = null;

    SimpleDateFormat utc = new SimpleDateFormat("yy-MM-dd hh:mm"); //this
is the trick. You can set it "yyyy-MM-dd hh:mm:ss". y and Y means
different, and M & m, d &D, check Java API.
    utc.setTimeZone(TimeZone.getTimeZone("UTC")); //set time zone
    timeString = utc.format("your Date obj");

This is a very non-standard date format. Why choose this particular one?

N.b., whether a format is standard really only matters if you are sharing
results with others, but I am curious nonetheless.

If it were 2007-01-26 17:47 it would be a fairly common format for
timestamping log entries. It has a very large advantage over other standards
in that that it's ascii-sortable so it is trivial to merge log records and
preserve temporal sequence (assuming you're using UTC as your timezone;
daylight savings can mess this up otherwise).

Dropping the century makes it suck, though, because it's then gets
confusing whether you're using this format, or the common US/Euro
shorhand m-d-y and d-m-y.

Use of the space character ' ' in lieu of the 'T' between the date and time is
widely accepted for practical use.

or if so, which one:

07-01-26 =>
July 1, ??26 vs. 7 January, ??26.

Except that these formats really use '/' not '-'.

DateFormat dateFormat = new SimpleDateFormat("yy-MM-DD HH:mm");
// You'll find more info about the pattern strings
// in the API doc of SimpleDateFormat

Date date = ...;
String s = dateFormat.format(date);
