Yeah, I chose something that was most likely long enough to hold anything that I
needed to put in there. It looks like Johannes found it to be a maximum of 33
characters, and after looking, the current maximum length is 30, so should I use
33 or 30?

Okay, I will fix this.

Yeah, I really wasn't sure how to do this properly.

Probably a good idea.

Yikes! I would have to agree.

When reading the timestamp in gmdate(), PHP doesn't care what timezone the
default is set to and it just displays what the time is based on the how many
seconds past the Unix epoch. Because of this, you have to get the timezone's
offset (which is in UTC from the database) and do the math to make sure it's
correct. I have verified this in a PHP shell. Changing the default doesn't make
sense to me also because the application is only displaying other timezones, not
working in them, only UTC.
