Hi,
Normally AP synchronize it's clock with controller at the time of adoption applying time zone setting from participating rf-domain. This should be always enough for mentioned tasks. NTP is a CPU consuming process and should be used on AP as exception if required. Please make sure that
1. IP is running, routing is ok and NTP server reacheble.
2. "ntp server 0.es.pool.ntp.org" (or similar) is specified on AP profile level or device context

Hi,

Can you confirm 2 things.
1) Are you using host name or IP address to define NTP server.
2) If using host name can you confirm that you have a proper DNS server defined.
Test to make sure it is working by pinging a URL like for instance www.google.com

Note:
If you know the IP address of the NTP server try using the IP address and running the 'show ntp associations' command again.
