It appears the RCI script for the Digi CP GW I'm using, the Digi X4 Gateway, does not retrieve the RTC setting correctly in response to <device_stats> .
There may be issues with RTC update rates, or simply what is read back in response to a <device_stats> request.
For example at approx 17:30 UTC on July 9 I queried an X4 using the RCI XML script in previous post. Here is what was returned:
<datetime>Wed Jul 2 15:22:46 2014</datetime>
The X4 is running Digi FW rev 2.17. Not sure what's going on here, of course I expected current UTC time to be returned.
