Date format in logs

Is there any reason to use MM-DD-YYYY for date representations in logs?
I think that it's non-standard and it's only mainly used in USA [1].

I suggest using ISO 8601 date format or preferred format based on locale.

ISO 8601 for file names in log.text will also allow autosorting by date of log files based on file name.
