6921 issues firmware and time

Hi.

 

I have this problem with the 6921 phone's, initialy the corporate directory doesn't worked with this particulary type of phone, an upgrade resolve the problem, the upgrade was to 9.4(1) SR1, now that phones with the upgrade firmware are showing the time incorrect, doesn't recognize the Timezone GMT -6 (Americas/Mexico City) and the time show an UTC -+ 0, Now when i try to downgrade to 9.0.3.0 the action was unsuccessful, i want to do the downgrade because the phones with firmware 9.0.3.0 show the correct time.

 

Is a CUCM 7.1.5

 

Any ideas?

 

Thnks.
