Please note, let not my remark stop you to create a common cron based scheduler, this would be already be a great step forward.

I *believe* the current scheduler by Maciej uses 'unix' timestamps which are not subject to daylight-savings rules. (At least, that is the only time format the NMWG classes have understood AFAIK.)

Hi

Jeff, You're right, it uses unix timestamps, so it's daylight-savings rules independent.

Nicolas, AFAIK we don't intend to write cron-based scheduler. We have one written by Loukik and used in his service only (which seems not to be developed any more?).

I wrote SimpleScheduler which is, in fact, the simply cron functionality. It's sufficient for most of my requirements (LSCleanup, LS registration component), but of course should be extended by more advanced configuration (with NMWG?).

Best regards
Maciej
