I like storing unix timestamps... because it makes it easier on the PHP side (for me anyway). I believe it's easier to work with YYYY-MM-DD HH:MM:SS when it comes to mysql
I used to be a hard-core UNIX timestamp man. Ever since I found FROM_UNIXTIME() (for converting a UNIX to MySQL timestamp) and UNIX_TIMESTAMP() (for doing the opposite), MySQL stamps have become more appealing - primarily because they're easier to read from the command line. If you don't see yourself going to the command line very often, I'd stick with a UNIX timestamp because like ~Ninja said - they're easier to work with in PHP.
Real programmers don't comment their code. If it was hard to write, it should be hard to understand.
yea the only thing that really bugs me about timestamps is that when I look at records in the database via phpmyadmin, I can't tell immediately what the dates are... I have to convert them to human-readable format before I know... which kinda sucks when you're just trying to see the time and date of a record real quick.
