Mod Comment edit by bakunin: please, instead of using some myriad of markup simply wrap CODE-tags around your sample. Its easier and at the same time easier to read too. Thank you.

May be you are on solaris/sunos, try this

Code:
nawk 'BEGIN{
	    mon="JanFebMarAprMayJunJulAugSepOctNovDec"
	   }
	  {
	   if(match($0,/...[[:space:]]..[[:space:]]..../))
	   {
	     m = substr($0,RSTART,RLENGTH); split(m,A)
	     gsub(m,sprintf("%02d/%02d/%04d",(match(mon,A[1])+2)/3,A[2],A[3]) )
	   }
          }1
     ' file

Please Note : I assumed that date will be same and time is changing in your file

Change awk to nawk

As Don says always,

If you want to try this on a Solaris/SunOS system, change awk at the start of this script to /usr/xpg4/bin/awk ,/usr/xpg6/bin/awk , or nawk

Screen idle
Thanks for your reply again. I changed as per your instruction. /usr/xpg4/bin/awk. But the screen is idle and nothing seems to be running. Cursor stays in next line and no execution at all.
