If you're the type to leave at three, it helps to send lots of emails as soon as you start working. People notice timestamps earlier than 6am.

This was my most recent specific recommendation, just send out an email right when you get in. Maybe do a peer review or push a commit. Anything small that shows the team you were there doing work.

Then you prep it the day before so you just have hit send, then you script it, cron it and sleep in:)
