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, Charles mailto:[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]
