I found a useful discussion here: [tag.readAll returns different quality (vs tag.read)](http://forum.inductiveautomation.com/t/tag-readall-returns-different-quality-vs-tag-read/8501) which is many years old and says issue was fixed in 7.6 (currently running 7.9.8)

I did a comparison with readAll and read and found the timestamps are different. read gives the correct value, readAll is showing “current”

```auto
qv =system.tag.read('[default]tank/tank_018/TkTemp/value')
aqv = system.tag.readAll(['[default]tank/tank_018/TkTemp/value'])
for x in aqv:
	print x.quality, x.timestamp 
print qv.quality, qv.timestamp
```

Output is:  
Disabled Fri May 31 18:15:12 EDT 2019  
Disabled Thu Jan 10 00:53:30 EST 2019

So issue quality attribute was fixed and timestamp is still different?
