Date() confusion

[Captain Dondo]

I have a value representing seconds since epoch (the number of seconds
since midnight Jan 1, 1970).

I want to disply this as Month, Day, and Year: MMM-DD-YYYY.

I've read about the Date() object but I am a bit confused.... How do I
get the year given seconds since epoch?

Thanks,

Javascript Date Object uses Milliseconds from the epoch

var NumOfSeconds = 1145554709;
var NumOfMilliSeconds = NumOfSeconds*1000;
D = new Date(NumOfMilliSeconds);

var Month = D.getMonth()+1;
var Day = D.getDate();
var Year = D.getFullYear();
var DateString = Month+"-"+Day+"-"+Year;
alert(DateString);

That's unreasonable or inadequately described; one almost always has
seconds since 1970-01-01 00:00:00 UTC (really GMT), where the TLA is
important. Also, midnight usually means the end of the day - consider
"I'll see you tomorrow, at midnight".

Silly format.
Month needs only two digits, and one writes Mon for the TLA.

But did you read the newsgroup FAQ, as posted Mon/Fri??

You can use

new Date(sec*1e3).getFullYear()
or new Date(sec*1e3).getUTCFullYear()

depending on requirement. If you want the year in a location other than
"Greenwich" or user's local, that's harder, but can always be done if
the TZ string is known - see in my js-date5.htm .

Then the date in proper standard form can be got, for example, with code
(in include1.js, shown in js-nclds.htm) such as resulted in :-

function anonymous() {
/* Date.ISOlocaldateStr YYYY-MM-DD */
with (this)
return getFullYear()+'-'+LZ(getMonth()+1)+'-'+LZ(getDate())
}

or with such as

with (Dobj)
S = String((getFullYear()*100+getMonth()+1)*100+getDat e()).
replace(/(....)(..)(..)/, "$1-$2-$3")
If you must have MMM-DD-YYYY, start with YYYY-MM-DD and adapt it.
