Having an issue with one of my MXe-III controllers running 9.2 where the clock is lagging. Over the past 2 weeks, I've reset the clock a few times. This week I started to document the time differences. I set it on Wednesday morning and it was about 2 seconds ahead of network time at that point. 24 hours later and it was already 20 seconds behind. This morning, it was 50 seconds behind. It was initially set to use our NTP server for time, but then it was showing 7 minutes behind despite the NTP server being spot on. I've also tried syncing with nist.gov and even Google's public NTP server but had similar issues. Any ideas what might be causing this? I have a few other controllers doing similar but this specific controller is the most extreme.
