This post is set to publish so the time stamp (in Unix time format, which is seconds past since the Unix time epoch… bla, bla, bla) is 1234567890. Yes, me and every other geek on the whole internet just published at the exact same second for the exact same reason.
So, this short line of code (<?php the_time('U') ?>) adds the time when I hit publish: 1234546280
Okay. I have no idea why the timestamp overshot by almost 2 hours there. Anyway, you get the drift…
