Set-PSUCache -AbsoluteExpirationFromNow does not expire

I understand that the following cache variable should expire after 6 minutes.

Set-PSUCache -Key “SavedText1” -Value “Saved text 1” -AbsoluteExpirationFromNow ([TimeSpan]::FromMinutes(6))

However, it is still available 40 minutes later. I can retrieve the value from cache and can also see it on the portal.

Hey @ivanl , Ive tried it here as well and can see the same behaviour in 5.4.1

I can see a number of issues with the expiration behaviour. Once I read a cached item it doesnt expire regardless of if its using absolute or sliding windows. seems like a bug

Ill log one i github for it now
