Debug log date time format

[mhkid]

How do I format the log file so the line shows date / time instead of the numbers it's showing? I've searched in the forum but don't see it and I'm sure it's got to be out here somewhere. But mine looks like this:

12901564 TSF:MSG:READ,1-1-0,s=1,c=1,t=0,pt=7,l=5,sg=0:64.6

@mhkid the value you see is the millis() timer, so doesn't show the actual time.
There are serial monitors that can add a timestamp in front of each line. YAT for example
