Exist some PE function to retrieve the timestamp of an archive value?

Hi all,

Reviewing all PE Functions in some docs like PEReference.chm, i can not find a function to to retrieve the timestamp of an archive value?.

I have found things like: NextEvent('PI TAG',ParseTime("t-1s")) but not function like XXX('PI TAG') which returns the timestamps of PI_TAG value.

Doesn't exists?

Thanks in advanced.
