better late than never ... We have the same problem here. I cannot present a solution, but a workaround. I too stop FTP Voyager Scheduler in the evening before Daylight Saving Time starts or ends. The day after, I open the file Scheduler.Archive (in ..\Programs\RhinoSoft\FTP Voyager\) in an editor. Then I search for "next run time". The entry "Val" contains the timestamp for next runtime in unix-format (seconds from 1970-1-1). You can charge the current time or the time, when the task should run for the next time on
http://7070.org/docs/timestamp . After you changed the value for each task, you can start the Scheduler again - and it should work without problems.
This also works if the Scheduler still runs when DST starts or ends. In this case you have to stop the Scheduler (and / or the service, if it runs like this) and change the value.
