WordPress apparently has no understanding of time zones, at least in the sense that makes sense – it displays all times in the local time of the viewer (at least, I hope it does… the alternative is that it displays all times as PST, which would be highly suspect). So all my old, imported posts, written way back when I lived in Australia, show up as having been posted about 17 hours ahead of reality.
So no, I didn’t write all my journal entries between midnight and eight in the morning. Just ignore WordPress – try not to make eye contact as you back away, slowly…
