This question already has an answer here:

Command stat -c%w /home/knezi/file returns just dash. It means, according to the documentation, that the date of birth in unknown. I've tried plenty of files but all with the same result.

The question is: do I need to turn on timestamping of filesystem (note that last access and modification work)? Or what else could possibly be the problem?

I'm running Arch Linux - 64b, FS ext4 (tried also on tmpfs).
