But it doesn't work. I get error:

1. you must have single space on both side of opening and closing square bracket.
2. sleep1 should be sleep 1
3. In comparison, you didn't use quotes. ( you will have spaces in both the variables)
4. you are comparing string with integer operator.

Code:
#!/usr/bin/ksh
NewTimestamp=$OldTimestamp
while [ "$NewTimestamp" = "$OldTimestamp" ];  do 
   sleep 1 
   NewTimestamp="$(date -r $CsvDir/$CsvFile)"
   echo "old: $OldTimestamp"; echo "new: $NewTimestamp"
done

EDIT: semicolon is necessary only when you have two separate commands on a single line.

NAME

       update-squidguard - Update script for SquidGuard.

SYNOPSIS

       update-squidguard

DESCRIPTION

       This script performs a database rebuild for any blacklists listed in the default Squidguard config file `/etc/squid/squidGuard.conf'.
       After rebuilding the databases it will reload Squid / Squid3 so that it will make use of the updated lists.

OPTIONS

       -v | --verbose
	   Show some more information and switch on progress bar when updating database.

       -c | --checkdb
	   Check Berkeley DB version and rebuild full database only if Berkeley DB version have changed. This option should be used after upgrade
	   of squidguard to reduce wasteful wait time.
