I'm using the Sierra Wireless GX440 and the RAP adaptor to track vehicles. Sometimes I'm receiving events with an odd date/time stamp of 11/30/1999 with varying times. I also receive date/time stamps of 11/30/2099 with varying times. I've tried filtering out these anomalies a couple different ways with no success. For example using Epoch milliseconds "TimeStamp >= 1448034146471" (11/20/2015 15:42:26) and "TimeStamp <= 4099698000000" (11/30/2099). Using that method no events come through. I've also tried "TimeStamp >= 2015y 11M 19d" with no success.
Is there any other way to filter these odd dates out?
