IDENTIFYING OFFLINE DEVICE

[Tunde Oyeyemi]

@George Chelidze & @Spencer Lambert

Thanks for the suggestion and my apology for posting the issue twice. I 
actually didnt see it listed on the mailing list, hence my second post.

Here is the logic i implemented and still testing:

I checked the _lastinform value and convert to unix datetime. I then get 
the different between the time of API call (current time) and 
_lastinform. If the different is more than my CPE periodic inform 
interval(I use 10 minutes periodic inform interval on the CPEs), i infer 
the CPE is offline and exit the API call. Otherwise, the CPE is online 
and I execute the API call.
