you can use date conversion script called script.sh:

#!/bin/bash  mydt() {    ifs='/' read -ra arr <<< "${1//[\[\]\\]}"    tz=':europe/london' date -d "${arr[1]}/${arr[0]}/${arr[2]}" '+%b %d %y %t' }  var1="$(mydt "$1")" var2="$(mydt "$2")"  echo "$var1" echo "$var2" 

then call as:

bash script.sh '\[10\/04\/16 01:02:03 bst\]' '\[06\/08\/16 05:02:08 bst\]' 

output:

apr 10 16 01:02:03 aug 06 16 05:02:08
