Assuming the first field(minutes) is not having commas and no starts in first two fields. Also it doesn't take care of the days if you have any. Probably you can work on that :

crontab -l | grep -v '^$' | grep -v '^#' |awk '{ gsub(/[ ]*,[ ]*/, ","); print }' | awk '{printf("%s,%02d,%s\n", $6,$1,$2)}' | awk -F, '{printf("%s runs at : ",$1);for(i=3;i<=NF;i++){printf("%02d:%02d, ", $i,$2)} printf "\n" }'

Also, I think you can easily work on formatting and converting to AM/PM.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
