507450 - Date() returns incorrect value (related to shunt)

Status: RESOLVED WONTFIX

(Core :: General, defect, P1)

Description

[Mike Beltzner [:beltzner, not reading bugmail]]

STR:

1. Double check system time
2. Open a new tab
3. javascript:(new Date())

Expected: same time as system thinks
Actual: a bizarro time (mine was GMT +2000, which doesn't exist)

Vlad suggests that this is a shunt problem. Apparently those words mean something, perhaps even something related to:

http://hg.mozilla.org/mozilla-central/file/d743242a080a/build/wince/shunt/time.cpp

Another way to notice this if you have a Zimbra account is to run a WinCE build and try to use your Zimbra Calendar. It's koo-koo-krazee!

Possibly related to bug 503710?

Perhaps even a dupe, yeah. It does look like we're just not formatting the offset correctly.

Comment 3

[Justin Dolske [:Dolske]]

Mine reports "GMT +1700", instead of "GMT-0700". Interestingly, I think that's correct relative to you, and the total is 24. Seems like something is getting a sign wrong somewhere.

Indeed (new Date()).getTimezoneOffset() reports -1020 on WinCE, but 420 on OS X.

So not a dupe of the other bug, but I will not be shocked if the fix still ends up being in the shunt code.

Mike, do you still see this?
