This is only usable if You add regional / city custom segments (other may apply) into the game and add a piece of code to Your tracking code. If someone has an easier way of getting the same data I would appreciate the info.
A short checklist:
1. Custom tracking code (Add a custom variable):
var escapeDate = new Date(); var escapeHour = escapeDate.getHours(); escapeHour = escapeHour.toString(); _gaq.push(['_setCustomVar',2,'Hour',escapeHour,2]);
Please note that you can change the variable slot, name and scope.
2. Create advanced segments - geo, content, sources etc.
3. Use and edit this Custom report as You see fit
