Hi,

It is not clear to me what you cannot achieve.

Basically you need to do 2 things:
1) Know how to make a date
2) Know how to break up your example String representation of a date.

1) according to the API:
var myDate = new Date(year,month,day,hour,minutes,seconds,milliseco nds);

2) break up a (date)string:
var myStringDate = "1999:01:23:01:30:12";
var myDateParts = myStringDate.split(":");

You now have an array myDateParts with all the substrings, splitted on :
So myDateParts[0] contains the year, myDateParts[1] the month, etc.

Hope that helps you going.

Regards,
Erwin Moller

var myDate= new Date();

This gives me the format
Mon May 08 2006 21:51:31 GMT+0800 (China Standard Time)

I was thinking if i write my own function to achieve 2006-05-08
21:51:31 ?

Yes. You can use a regular expression to solve this specific case, or you
can use a lib like my date library if you wish:
http://www.javascripttoolbox.com/lib/date/

Using the lib approach you would just do:

var date = Date.parseString("2006:05:08:01:02:03","y:M:d:h:m: s");

OK.

There was a brief explanation given on how the Date object works and
hints on how to start writing the code.
Although the example was the other way around.

var now = new Date();
document.write('Day of Week is now.getDay and gives: '
+ now.getDay() + '<br>');

Remember that the numbers it returns are zero based. You can find all
the Date components at:

im trying a simple example but it is just not working

var curdate = new Date();
document.write( curdate );
document.write( curdate.getYear() );

1st Output -> Mon May 08 2006 23:28:29 GMT+0800 (China Standard Time)
2nd Output -> 106

What is wrong here?

Thanks Matt for the advice earlier on

[ahjiang]

Not completely, since you are not quoting what you are talking about.

Methods giving that can be found via the newsgroup FAQ, see sig below.

You have not said whether you want civil time or UTC. Seek one of
these, where implementation is by adding a Method to the Date Object.

new Date().ISOlocalDTstr() // 2006-05-08 20:12:44
new Date().UTCstr() // 2006-05-08 19:13:16

Basics of code is readily seen in js-nclds.htm .

If your are writing only for local use, and if the local settings are
sensibly in conformity with ISO 8601, then consider

new Date().toLocaleString() // 05/08/2006 20:18:03

Note, of course, that in my system Microsoft has not got it right.

Erwin, Matt : you omitted to notice the absence of a central colon.

OP : Date Objects do not have a format, other than IEEE Double of
milliseconds from UTC 1970.0.

Randy : He wants date, not Day-of-Week. Javascript getYear, Day-of-Week
and Month are non-standard; other results are normal, without improper
use of zero.

No, it does not. It assigns a reference to a new Date object to `myDate'.
When this reference is passed to window.alert(), the object's toString()
method is called, which returns the date in the above format.

(I cannot know what you are thinking, so please don't ask me.)

However, Date objects have several retrieval methods (their identifiers
starting with `get') that you can use to create the Date format you want.

yes.

var myDate= new Date();

myDate only holds two things:

1 the fact it is a date object.
2 the number of miliseconds since the beginning of [Javascript] time,
being 1970/1/1 00:00:000 GMT/UTC

It does not hold any format not even the timezone at creation.

Try:

var beginningOfTime = new Date(0);

alert(beginningOfTime);
// local time at beginning of GMT time
// .toString() is implied here

alert(beginningOfTime.toUTCString());

Your pedantics are amusing sometimes. What is more amusing is your
ignorance at times.

And all this to reply to a dead 9 day old thread. I am impressed with
your prompt replies.
