Timestamp In ISO8601

Would you all mind changing the format that orders get timestamped on export from what it is to something closer to ISO8601? As it is, Excel doesn't know what to do with it. If it were ISO8601, Excel knows what to do with it. The T in the middle is not necessary, but if the export follows the format of 2017-11-02 11:52:45 Excel is able to convert it automatically to a time.
