To sort dates it works best to convert them to epoch seconds - the number of seconds since Jan 1 970. This code adds an epoch time sorts based on the epoch time, then prints the original minus the seconds: this assumes some kin of linux OS -
Code:
while read dt 
do   
   echo $(date -d "$dt" +%s) $dt;    
 done <  file | sort -k1n | awk '{printf("%s %s %s %s\n", $2, $3, $4, $5) }'

Called a tag sort.
I get this output:
Code:
Jan 20 16:27:38 2020
Jan 20 16:29:51 2020
Jan 20 16:44:39 2020

@Drl - one of our senior people, may mention getting a linux package for date operations, one of the commands is "dsort" which does exactly what the code above does. Hopefully he will mention where to download it. I do not know
