SIP invite error missing time zone

[burb72]

Path is customer managed cucm and cube to sipt to an adtran we manage for them.

Calls from other locations are good. But calls from this location fail to the error:

12:02:57.442 SIP.STACK MSGSUM
Tx: SIP/2.0 400 SIP Parser Error : Missing TIME ZONE, line 12, column 33
(with SDP)

But at line 12 column 33, I show a time zone:

seems adtran doesn't accept edt in the date field in the invite, has to be gmt or no date field

CSCvf07153 Cisco CUBE uses incorrect timezone in SIP messages. If you haven't seen this.
