The provisioning feature will not complete if the earliest date is set more than 4 hours in the past. The reason behind this is that when computing the tiny URL expire date the formula "earliest date + 4 hours" is used. This is fine when it is in the future, but for past dates, this leads to tiny urls that expire before they are created. Stumbled over this when working on another bug.
fixed in rev 133468.

I tried setting a date in the past, and this works. As a result, I'm moving this to VERIFIED.
The web UI seems to just convert a date in the past to the current time and schedule the event for then, regardless I think this is expected. Release pending.
