Hi All,  
I am exporting/importing reference tags (inside UDTs) along dev/test/prod environments. Some of the reference tags qualities are uncertain. For these, it appears that the imported reference tags have a timestamp sooner than the source tag. Is there a way to ensure a reference tag time always matches the source tag timestamp?
