System time on the server is correct. The SPA504g phones are an hour fast.
I’ve not altered the default $model.cfg file, which shows these time-related entires:
Perhaps related, I’ve altered the display name on one of the phones in question and it doesn’t change on the phone. I do have option 66 set in DHCP and pointed to the FreePBX server.
The one Polycom speakerphone is also an hour fast.
CDR and voicemail recordings list correct time.
FreePBX Distro is current (as of today), and all modules are current as of today.
