My custom site and this site have the current year displayed. Mine is a php element that is used by most pages, this one.... dunno actully. Could be a setting... Need to look into that. Mine is a manual change I do (generally) in early Janurary. But I've often considered making the year auto-update. But there's so many reasons why I don't. For one, the date is based on the server time, which won't align to everyones time so it's going to be at least slightly late/early for most anyway. But also I don't trust glitches that could cause the date to be something silly in the future or the past, and I'd feel the urge to check it every year.... and maybe even during the year. And.... I'm not a lawyer and I'm not sure of the legality of an auto-copyright statement. So yeah. Every year I manually update it.
Funny stuff.
