Eh, 6am leave time aint that bad. Totally sounds worth it if for nothing just to say you worked in the playboy mansion at worst and at best... well who knows. That's really cool and exciting. Ya never know what door opens when you try something different and/or make sacrifices.
Leaving early for me doesn't really require manager approval. THere's no set start/end times, but just about being responsible since if I leave, then there's no one supporting our largest data center, so got to make sure people are aware. I also left the house shortly after 6am today to get in nice and early and make sure I earn that cash since leaving early means losing an hour or so of pay.
