I have the PRS-500, but cannot find the manual. Can somebody please tell me how to set the time on this thing? I can turn it on/off, 12/24 hour, etc, but not set it.

Just plug it into your computer's USB port and run Connect or eBook Librar and it will set the time based on the time of the computer.

Thank you. I have not connected in awhile other than to charge the battery.

If you don't connect in a while, the clock can get off.
