I was shuffling a meeting for next week around today and noticed that only Arturo and I have working hours set in our Google Calendar profiles. I think it would be useful for everyone to configure their calendar to show their comfortable working hours to make it easier for me and others to set meetings without doing a lot of mental math about if it is too early or too late for someone to join. You do this by clicking the "cog" icon in the gcal UI, selecting 'Settings' and then 'General > Scheduling' in the left hand navigation menu.
