Got a negative number from file.dateLastAccessed

[evenrain]

import SWFKit.*;

f = new File("c:\\test.txt");
d = new Date(f.dateLastAccessed);
trace(f.dateLastAccessed);
trace(d.toLocaleString());

I got result from above code:
-347827083
Sun Dec 28 07:22:52 GMT+0800 1969

why the return value of dateLastAccessed was a negative number?

[SWFKit]

Yes, the "dataLastAccessed" property returns a 64-bit integer, but the "trace" method output any integer as 32-bit.

but the last accessed date was wrong, either....

I want to select those files modified in 24 hrs, how do I do ?

[SWFKit]

It will return a correct time value, unless the file does not exist. To check if the file has been modified within 24 hrs, you can

d = new Date(f.dateLastModified);
f = new File("c:\\test.txt")
var cur = new Date();
var modifiedWithin24hrs = (cur.getTime() - d) < 24*3600000;
trace(modifiedWithin24hrs);

The file was modified in "Fri May 23 09:35:45 GMT+0800 2008"

I wrote my code:

f = new File("c:\\test.txt");
d = new Date(f.dateLastModified);
trace("file: " + d.toLocaleString());
var cur = new Date();
trace("cur:" + cur.toLocaleString());
var modifiedWithin24hrs = (cur.getTime() - d) < 24*3600000;
trace("in 24 hr?" + modifiedWithin24hrs);

, and I got the result:

file: Mon Jan 5 02:29:27 GMT+0800 1970
cur:Fri May 23 09:46:40 GMT+0800 2008
in 24 hr?false

The file's Last Modified Date was wrong.
