1:23am. Do not the timezone shifts happen at 2am (avoids horrible day changes if it happened at 12am). So 1:23am can happen twice if 2am steps back to 1am.
Our summer time just ended here. Might a similar shift have happened for you?
Well, except that the format of the crontab is....
Minute Hour Day-of-Month .....
How does that avoid the problem? The same time can still happen twice.
????
How can 23:01 happen twice at the switch to/from DST?
