Yes, we've had a similar issue before, in our case MESH side DCS time was ok, AIM time was not and Nodebus side time changed. We needed to update/quickfix AIM and the BTK was not set. (Either was never set or SysDef wacked it). We hold our breath every time we restart and make sure everyone knows the time may change. Our MTK and BTK are both MESH boxes. Hope the info helps.

This caused all historians to flat line for seven hours. This box has been rebooted before without problems. QF1011666 that was supposed to correct time related issues was previously installed on this box. The MTK with No GPS is on the MESH AW Ver.8.4.1 and the BMTK is on a Solaris AW Ver. 7.1.4 on one of 11 Nodes. My question is; Has anyone else had this problem and been able to resolve it. Also is there a way to detect before a reboot that a time jump is likely and prevent it.
