Adding date to the logs

I only run vanilla servers and go to the server, then logging, logs/latest.log and it has the time (xx:xx:xx).
Is there anyway to the date to that output?
(mm/dd/yyyy xx:xx:xx)
I do not have log4j or anything like that.

Any help would be appreciated.

I do not have log4j or anything like that.

I do have log4j it seems.
Looking around reddit and found that I can add the following to the launch arguments:

Dlog4j.configurationFile=<path to config file.xml>

Where would I place this in mineos?
