System: FreeBSD wwweasel.geeksrus.net 4.4-RELEASE FreeBSD 4.4-RELEASE #0: Sun Oct 28 04:44:34 EST 2001 root@wwweasel.geeksrus.net:/usr/src-4.4-RELEASE/sys/compile/WWWEASEL i386
>Description:
1. 'at now + 1 minute' is allowed.
2. 'at now + 0 minutes' is rejected with 'trying to travel back in time';
that's a different PR.
3. 'at now' is intuitive, and I can't think of a good reason to disallow it.
>How-To-Repeat:
Try 'echo foo | at now'.
