However I've been running release versions of OpenBSD with the following definition: ~ ~ ~ * * /my/task/goes/here && /usr/bin/logger -t foo "Task done" Feb 18 18:09:01 foobar foo: Task done Mar 18 18:09:01 foobar foo: Task doneMar 24 23:42:01 foobar foo: Task doneApr 20 11:41:01 foobar foo: Task doneMay 16 18:24:01 foobar foo: Task doneJun 6 17:24:01 foobar foo: Task doneJul 6 17:24:01 foobar foo: Task doneAug 6 17:24:01 foobar foo: Task doneSep 6 17:24:01 foobar foo: Task doneOct 6 17:24:01 foobar foo: Task doneOct 31 08:44:01 foobar foo: Task doneNov 19 12:02:01 foobar foo: Task doneDec 19 12:02:02 foobar foo: Task done Surely it would be clutching at straws to describe an event happening at exactly the same time 5 months in a row (Jun–Oct) as genuinely statistically random ? The same with Nov & Dec. Especially given three of my crontab fields are supposed to be random (minute, hour, day-of-month) I would expect to see at least one of the three to be different ?!?
