Time & date always reset after rebooting.

[H3nry]

Hello,

I have issues with T42S using SfB firmware 66.9.0.25.

Everytime I reboot the device, the clock always go back to 30 Sept 2017 00:00.

I have experiment the following
1. DHCP on, NTP high, Manual disabled
2. DHCP on, NTP high, Manual enabled
3. DHCP off, NTP low, Manual disabled
4. DHCP off, NTP low, Manual enabled

Supposedly if Manual time is enabled, the phone should retain it's setting right ?

I don't have the issue when originally running T42S standard firmware 66.81.0.70. Meaning the phone can get the correct time either via DHCP or via NTP server.

On other brand IP phone (Polycom VVX), they have no issue getting from NTP server.

Any ideas ?
