Is that what the data looks like, or are the lines actually really long?

Will the process name always be NEWOLUF2?

Here's what I have so far, assuming the long lines were wrapped accidentally. It's much, much, much easier to write when you know what you're supposed to be operating on
Code:
$ cat begintrans.c
#include <stdio.h>
#include <string.h>
int main(void)
{
char buf[16384];
int transcount=0, elapsetotal=0;
while(!feof(stdin))
{
int newoluf=0, elapsetime=-1;
char timestamp[64]={0};
buf[0]='\0'; // Blank out buffer
while(strcmp(buf, "BEGINTRANS\n") != 0) // look for BEGINTRANS
if(fgets(buf, 16384, stdin) == NULL)
break; // EOF
if(feof(stdin)) break;
while(strcmp(buf, "ENDTRANS\n") != 0) // Look for ENDTRANS
{
const char *tsstr;
if(fgets(buf, 16384, stdin) == NULL)
break;
if(strstr(buf, "NEWOLUF2") != NULL)
newoluf=1;
if(tsstr=strstr(buf, "Timestamp"))
sscanf(tsstr, "Timestamp <%[^>]>", timestamp);
if(strncmp(buf, "ElapseTime", 10) == 0)
sscanf(buf, "ElapseTime <%d>", &elapsetime);
}
if((elapsetime>=0) && (timestamp[0]))
{
transcount++;
elapsetotal += elapsetime;
printf("trans %d, elapsetime %d, timestamp %s\n",
transcount, elapsetime, timestamp);
}
}
printf("Average elapsetime is %d\n", elapsetotal / transcount);
return(0);
}
$ gcc begintrans.c -o begintrans
$ ./begintrans < data
trans 1, elapsetime 745, timestamp 14Sep1111-07-37
trans 2, elapsetime 765, timestamp 14Sep1111-07-37
trans 3, elapsetime 579, timestamp 14Sep1111-07-37
trans 4, elapsetime 356, timestamp 14Sep1111-07-38
trans 5, elapsetime 651, timestamp 14Sep1111-07-41
trans 6, elapsetime 292, timestamp 14Sep1111-07-42
trans 7, elapsetime 345, timestamp 14Sep1111-07-52
Average elapsetime is 533

Why would you need to use this in a script?
Why can't you just use print to print out what you want printed in the begining and print for what you want at the end.
So this:
nawk 'BEGIN {print "this is the first line"}
{print $1 $2 $3}
{print $5 $6}
END {print "this is the last line"}'

pam_timestamp_check
PAM_TIMESTAMP_CHECK(8) Linux-PAM Manual PAM_TIMESTAMP_CHECK(8)NAME
pam_timestamp_check - Check to see if the default timestamp is valid
SYNOPSIS
pam_timestamp_check [-k] [-d] [target_user]
DESCRIPTION
With no arguments pam_timestamp_check will check to see if the default timestamp is valid, or optionally remove it.
OPTIONS -k
Instead of checking the validity of a timestamp, remove it. This is analogous to sudo's -k option.
-d
Instead of returning validity using an exit status, loop indefinitely, polling regularly and printing the status on standard output.
target_user
By default pam_timestamp_check checks or removes timestamps generated by pam_timestamp when the user authenticates as herself. When the
user authenticates as a different user, the name of the timestamp file changes to accommodate this. target_user allows to specify this
user name.
RETURN VALUES
0
The timestamp is valid.
2
The binary is not setuid root.
3
Invalid invocation.
4
User is unknown.
5
Permissions error.
6
Invalid controlling tty.
7
Timestamp is not valid.
NOTES
Users can get confused when they are not always asked for passwords when running a given program. Some users reflexively begin typing
information before noticing that it is not being asked for.
EXAMPLES
auth sufficient pam_timestamp.so verbose
auth required pam_unix.so
session required pam_unix.so
session optional pam_timestamp.so
FILES
/var/run/sudo/...
timestamp files and directories
