How to get the property of tags?

[zcattacz]

I would like to use the timestamp of the tags to store their values.
I retrieve the values in batch by client.read_values(tags), how can I retrieve the timestamps also ?

I am using KepwareEx, I have enabled Browsing>Return Tag Properties in Project Property and Reinitialize, but still for prop in await tag.get_properties(): print("prop:",prop) returns nothing. Even if this works this searches all the props for the timestamp property, is there any more efficient way ?
