Date.difference() fails on dart2js in checked mode

[alan-knight]

The Date.difference() operation fails in dart2js in checked mode. e.g.

main() {
  var localDate = new Date(2012,8,9,10,30,23,0,false);
  var utcDate = new Date(2012,8,9,10,30,23,0,true);
  var x = localDate.difference(utcDate);
  print(x);
}

 ~/dart-repo/dart/out/ReleaseIA32/d8 out.js
out.js:388: 1344533423000 does not implement int
  throw $.captureStackTrace($.TypeError$($.S(value) + ' does not implement int
          ^
1344533423000 does not implement int
    at [object Object].captureStackTrace (out.js:599:18)
    at [object Object].intTypeCheck (out.js:388:11)
    at DateImplementation.difference$1 (out.js:32:56)
    at [object Object].main (out.js:920:67)
    at out.js:1017:5

I reproed this too. You can just use:

var d = new Date.now();
e = d.difference(d);

Currently I am blocked on changes to the unit test library because of this.

I guess you can work around the issue by not using checked mode when compiling to JavaScript using dart2js? I'll work on a fix.

Hi Kasper, any progress on this issue?

The date.valueOf returns an integer outside the 32 bit range which (currently) says that it is not an integer.

Added Duplicate label.
Marked as being merged into #3720.

PSA: I think Nicolas just fixed this in r12018.
