two issues
one the Cisco AP's do not have a clock like your PC if you set the time manually when the AP loses power or reboots the time is reset to the default and you need to set it again.
te]wo the better solution is to designate a time server for the AP to syncronize to.
either method can be configured by clcking services on hte WEB interface and then select NTP or SNTP depending on you IOS version. then entering the time server IP address in the proper box or typing in hte proper date and time in the fields below, if you select the time server method the date and time will be filled in automaticaly once the time is syncronized.
