I have our Access Points and Wireless Controller set to use our Firewall as a NTP server. However randomly these Access Points will stop syncing correctly and their times will become several minutes faster. This causes the devices we use on our wireless to have the time displayed according to whichever AP they're connected too which can cause issues with clocking in and out.
My question is, what is causing the Access Points to stop using the NTP servers time?
Relevant spec information:
Wireless Mobility v5.4
Not exactly sure the firmware version is being run.
