Sounds more like it is only a problem on the _day_ DST changes. DST usually changes at 02:00, so I'm guessing that on the day of change, when a new log is being rotated, the new day is having 1 hour adjusted when the file name is being calculated at 00:00 (day change) This should not occur, until 02:00 (dst change). There is a possible problem: lets say you have hourly log rotations, at 02:00 when the time changes back, does xmail open the 01:00 log and append? The scenario of adding 1 hour is not a problem, there will be one log 'missing', because the hour was skipped -02:00 became 03:00 Rob: -) _ Signature: Live like you'll die tomorrow!

How do programs such as MRTG and RRD compensate for this screw up? RRD is designed so that all data must be consecutive times, and no less than one second apart, going back and redoing the hour would result in errors for the data capture routine, and skipping an hour would make a hole in the data. -- Best regards, Charlesmailto:[EMAIL PROTECTED] - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]
