FreeBSD's cron(8) was taught about DST changes more than one year ago (look at the -s and -o options). I understand that this was a reaction to the fact that this very discussion bubbles up twice a year. PR bin/24485 tries to summarize a thread which took place in some FreeBSD mailing list (and to provide a place to point to should one more user come and ask around DST change time). While porting over OpenBSD's code - which explicitely claimed to handle DST - didn't help, Sergey Babkin's commits addressed the DST "problem". Since I was merely annoyed by the ever popping up discussion I thought I could contribute or help by porting OpenBSD's code to FreeBSD. But since this was not a solution and I had no real need for a DST handling cron(8) I quickly got sidetracked. Those of you who want the cron daemon to handle DST "transparently" should try the above mentioned options and report back on successes or failures (the default behaviour is the traditional one). virtually yours 82D1 9B9C 01DC 4FB4 D7B4 61BE 3F49 4F77 72DE DA76 Gerhard Sittig true | mail -s "get gpg key" Gerhard.Sittig@gmx.net -- If you don't understand or are scared by any of the above ask your parents or an adult to help you.
