Although it's a tad more verbose, my inclination would be to accomplish a similar objective by specifying a (complete) time zone designation (if this behavior is wanted -- of course, if it's not specified, the scheduling is for "local time"). Among other things, that would permit scheduling something for a certain time in (say) the MET time zone on a machine that happens to live in the US/Pacific (or US/Arizona!) time zone. I can imagine circumstances where that might be of value. However, the ability to always use "standard" (or "daylight savings") time for a given crontab entry would also be of value. >I would like to add a warning for the user if they schedule a >job that happens during the magic hour....

Not sure this is needed. Someone goes back into the crontab, if there's something in there worthy of note, crontab should probably mention it. It's not unheard of for an SA to set things up a certain way, then go on to a different position, and for the original SA's successor to have a bit to clean up.... :-) Maybe there could be an environment variable to tell crontab that the person in question doesn't want to hear its nattering....
