 Made this for another site where I'm the webmaster, after extensive googling for something like this turned up nothing. The code is Copyright Euan Reid, 2009 (Euan Reid is, as some folk here know, my real name). Free to use and distribute, only limitation is that you share all the changes you make here for others. Oh, and that you can't sell it. You don't need to credit me.

If any of you DO google it and turn up a result on MMOwned.com, note that post is also by ReidE96. That's another forum I frequent, and I posted it there too.

 Shame it's copyright. Anyways, it's not like I'm selling it or anything, I just thought someone else may, at some point, want something like it, and I know how much effort it took. Until I learned about putenv.

I asked God for a bike, but I know God doesn't work that way. So I stole a bike and asked for forgiveness.

 Cause I don't know the time zone names aside from the US ones and GMT :P And I only know the US ones cause the website is in the US.

Edit: The server's timezone is PST, hence why it's the default. You can change it by changing which item in the dropdown has the "selected" part in it.

 had one but it is down now I will spend time making stuff in the summer which for me hasn't started yet.

Why not make something big? or do you not have the time for it?
