The TimeDiff match compares the time of values against the time it considers to be “now” and matches those values where the times differ more than a given threshold. It is intended to be used on server instances to filter out values from machines with a wrong time setting. Since the timestamp in RRD files must be ever increasing, inserting only one value with a timestamp far in the future causes big problems. The purpose of this match is to prevent exactly this problem.
