Time mismatch between controller and AP, why?

[btjtaylor]

Hello all,

I have a lab setup with a Cisco vWLC deployed in VMWare ESXI and 2x 1131 APs, 

The APs are failing to join the controller due to a certificate error. I have noticed that the time that APs are using is an hour out from the controller.

The controller time and timezone are set correctly (London timezone, it's currently summer time here so its GMT+1), but the APs are being set to an hour early (GMT+0) and are failing to join.

I tried setting the time manually on the APs, but as soon as they talk to the controller it sets itself wrong again!

How can I resolve this?

Thanks

Ben

You can't.  

LWAPP/CAPWAP standards do not include the APs to inherit timezones of the controller.  So the controller can have different timezones but the controller-based APs are always in UTC/GMT/Zulu timezones.
