Timestamp on phone not accurate

[nguira]

Hello,

We have a problem on an IPO 500v2 R9.1.7.0 Voicemail Pro Build 5

Our Phone are at the correct time, but when we go to the voicemail history on the phone, we can see that the date of the voicemal are not accurate, there is more than one month less than the right date.

Any advice ?

Is the time on your voicemail server correct? Is it running on Linux or Windows?
