Wouldn't you know it... eBay just broke something else that was working great.
I usually list between 15 and 20 items a week on 5 minute intervals.
This gives the items varied start times in the minute (i.e. 14:00:43; 14:05:18; 14:10:57)
When done I'd select them then go to 'reschedule' and reschedule them in the same time frame.
This gave me 14:00:01; 14:05:01; 14:10:01... so they'd all start every 5 minutes on the minute.

Enter eBay 'programmers' {sic} and now 'reschedule' tries to start your listings TOMORROW... While paying no attention to the clock.
Thanks bunches eBay... You did it again.
