The Cisco phones are an hour out

[adnanhassan1]

we are using CUCM 9.1.2. The Cisco phones are an hour out (i.e. it's 17:10 at the moment and our phones are showing 16:10)

I have checked 

ntp status 

utils diagnose module ntp_reachability 

ntp restart 

Can someone please advice if I need to upload any updated cop files etc?

Thanks

Are phones' device pools using proper Date/Time Group? Which time zone is the Time/Group referencing?

[adnanhassan1]

Yep they are in right date/time group

[adnanhassan1]

Time/Group referencing to GMT Europe/London

Which phone models are you using? If 79XX, what protocol SIP or SCCP?

we got 9971, 7941, 7965, CIPC 

all of them got one hour behind..
