Stream delay due to being out of regular time (6)
I believe the answer is:
jetlag
'being out of regular time' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'stream delay' is the wordplay.
'stream' becomes 'jet'.
'delay' becomes 'lag' (lag is a kind of delay).
'jet'+'lag'='JETLAG'
'due to' is the link.
Can you help me to learn more?
(Other definitions for jetlag that I've seen before include "feeling of disorientation" , "sickness from being transported" .)
