@ Daniel_Gate

Sorry, needed to rewrite the script, hope this will fit your needs. It will check if the next logged line is not more than 10 minutes or 600 seconds apart. Store the script into a script file:

Code:
awk -f check_log_time.awk logfile >outfile

Code:
    BEGIN{mon="dummy";d=0;t2=0}
    {
    {
    split($3,t1,":"); t=3600*t1[1] + 60*t1[2] + t1[3]; t3=t-t2
    {if ($1 ~ mon && $2 ~ d && t3<601) print "Difference to previous line sec: " t3 "\r" $0 }
    }
    mon=$1; d=$2; t2=t
    }

       igawk - gawk with include files

SYNOPSIS

       igawk [ all gawk options ] -f program-file [ -- ] 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
