--ZwgA9U+XZDXt4+m+ Content-Type: text/plain; charset=us-ascii Content-Disposition: inline I know I'm going to regret this, but since silence is being taken to be consent here, I'd better speak up. My opinion, for those keeping count: Changing cron to internally compensate for changing timezones seems to open more doors for bugs and misfeatures than it closes. FreeBSD is in use worldwide, and compensating for all the various timezone shifts has the potential to cause serious code bloat. If you don't catch all the possible shifts, it's hard to claim the solution is complete. I oppose such changes. If someone wants to change cron's behavior to make DST (and other timezone shenanigans) behave intuitively, add a flag to make cron work exclusively in UTC as someone else suggested. It's simple to explain which means less user confusion, and covers all the cases (even crossing the International Date line with a mobile laptop) which reduces code bloat. Finally it's conceptually simpler and more elegant. I think that's worth something. I don't think that changing cron's behavior for DST is a pressing issue. However, if a change is made, I support the change to using UTC (as a user configurable option, default off), not detecting and correcting for all possible local time mods. --ZwgA9U+XZDXt4+m+ Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.1 (FreeBSD) Comment: For info see http://www.gnupg.org iD8DBQE6XevXaUz3f+Zf+XsRAhRcAJ9IG7bRqGxC7poPhs8wAUcN+A0uQwCfT0WA Y37WeB/+2+PQDBaUdNb5mtY= =YSRv -----END PGP SIGNATURE----- --ZwgA9U+XZDXt4+m+-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
