Timezone problem Avaya J129

[viana1]

Hello guys!

I have a J129 phone and a 9611G phone with 46xxsettings configured.

At the 46xxsettings I have my timezone configured to America/Fortaleza.

But only for 9611G it shows the correct time. The J129 always show +3H.

For example, right now is 17:13... It shows 17:13 at 9611G screen's, but shows 20:13 at J129 screen's!

I used GMTOFFSET to adjust the time to '-03:00', so the time is now correct at J129, but this is the best practice? I mean, there are other better solutions? Why only J129 shows 'wrong time'? I know that "Olson name format" tell me that Fortaleza is -3H from GMT, but my 9611G phone don't have this problem, no need to adjust, only for J129.

Best regards
