As per WLA AE, DST came early for some [the "Azores" was one, ah, give me those sunny climes!]
Apparently there is a bug in TZ in which DST rolls over as pre-Dubya.
Till now, the workaround is to [a] change the affected job start times OR [b] update the TZ table.
It is my understanding that there is an official hotfix coming down the road, possibly this ones updates the reference file under the 'dbobj" dir.
Were any of you affected by this early change?
