Hello list,

man utimes says:
"The access time is set to the value of the first element, and the 
modification time is set to the value of the second element. For file 
systems that support file birth (creation) times (such as UFS2), the 
birth time will be set to the value of the second element if the second 
   element is older than the currently set birth time."

I can't set birthtime on ZFS although files appear to have it. Is it 
supposed to work? If not, why not? (On FBSD 11.0)

Please, cc me, I'm not subscribed to the list.

Regards,
Heikki Lindholm
