Intel AMT Alarm Clock with Version 5

[NWarr]

We are currently using AMT alarm clocks to wake up computers nightly. We have computers with Version 5, 7 and 8. We set the same alarm clock on all PC's through PowerShell and have some interesting results. AMT version 7 and 8 PC wake at the set time. Version 5 machines will wake about 3 hours later. I was wondering if anyone else was able to successfully set and wake AMT version 5 machines or if you were experiencing the same results. I should note that the AMT clock was set to be synced with the OS on provisioning.

I opened a support ticket about the matter and this is what I was told:

"This is a known issue across all AMT 5 platforms. Please note that the time drift bug will not be fixed due to the version 5 is end of maintenance phase."

Does anyone have a work around for this "Time Drift"

It is a good thing that we have support for these computers because I got the same thing from Intel that AMT 5 had a time drift bug. They haven't been able to provide any workaround yet.
