Tag quality timestamp

Ignition

I found a useful discussion here: tag.readAll returns different quality (vs tag.read) 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”

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?
