Re: PHP 4.0 Bug #8828 Updated: mktime using mday<=0

I would vote for C simply for the fact that I developer on Windows 2000 and Linux quite a bit and then I upload to either a Linux or Mac OS X box for testing and serving. This would mean that my local dev site will work and my testing or live sites will have problems with this command. Now I am aware of the issue so I will have to find a workaround for it or in a best case scenario I can depend on the tool (PHP) to correctly implement the function for me on all the target platforms. The latter being the preferred method.
