Well, try this based on MadeInGermany's proposal:
Code:
 awk -vDT=$(date +"%y%m%d%H%M" -d"- 3 hour") '
                 {sub(/^\[/,"")
                  split ($1, D, "/")
                  split ($2, T, ":")
                  AT=sprintf ("%02d%02d%02d%02d%02d", D[3], D[1], D[2], T[1], T[2])}
         AT > DT && /Exception/
        ' file
7/31/14 11:55:66 Exception found

which is fine as my local time is 31.07.14 14:07.

logsave

LOGSAVE(8)						      System Manager's Manual							LOGSAVE(8)

NAME

       logsave - save the output of a command in a logfile

SYNOPSIS

       logsave [ -asv ] logfile cmd_prog [ ... ]

DESCRIPTION

       The  logsave  program  will  execute  cmd_prog with the specified argument(s), and save a copy of its output to logfile.  If the containing
       directory for logfile does not exist, logsave will accumulate the output in memory until it can be written out.	A copy of the output  will
       also be written to standard output.

       If  cmd_prog  is a single hyphen ('-'), then instead of executing a program, logsave will take its input from standard input and save it in
       logfile

       logsave is useful for saving the output of initial boot scripts until the /var partition is mounted,  so  the  output  can  be  written	to
       /var/log.

OPTIONS

       -a     This option will cause the output to be appended to logfile, instead of replacing its current contents.

       -s     This  option  will  cause  logsave  to  skip writing to the log file text which is bracketed with a control-A (ASCII 001 or Start of
	      Header) and control-B (ASCII 002 or Start of Text).  This allows progress bar information to be visible to the user on the  console,
	      while not being written to the log file.

       -v     This option will make logsave to be more verbose in its output to the user.
