Countdown timer shows wrong number of days under Windows 8.1 in Internet Explorer & FireFox

The countdown timer is showing 1 day less than it's supposed to be under Windows 8.1, in Internet Explorer and FireFox.

In Chrome, under Windows 8.1, and in Safari, Chrome & Firefox under Mac OS X the correct number of days are shown.

You can test the issue on this site until May 19, 2015: https://apps.pxl.be/misc/timer/badtimer.html

shows one day less on Firefox for Mac as well.

Indeed, something that I found out 5 minutes ago.

Same here. We just launched a countdown campaign and this is not good!

I've created a work around by checking for the OS and browser of the client in ASP and then dynamicaly adjusting the end date (+1 day).
This works fine, but you need a way (PHP, ASP, ...) to do this.

Did the same :).
