Is raiding worth doing for me?

[sox7d]

I'm a 59 wizard, but I don't really have time to play the game intensively anymore. But I'm wondering what raiding is like? Are the high-end guilds like "yeah, we're doing gorenaire this friday, be on at 5 PM PST, we'll kill it then you can log off," do they batphone or is it still 20 hour poopsocks and FTE battles? For that matter, would a high-end guild even want a 59 wizard?
