Hi,  
I am reading the data from restAPI and storing the data with timestamp which is coming from API with storeTagHistory.  
and when last data is recieved I write to the tag,  
As I write to the tag the value gets stored in database with current time.

But the last value I had already saved using storeTagHistory and I am having a duplicate values with current time.

I am trying to restrict the last value getting saved after writing it to the tag.  
As this tag have read and write option I cannot put large deadband and leave it.
