Need opinions about scripting blackouts

Hi All.
I am stuck and need some fresh ideas...

I am writing a script that checks to see if an Oracle db is available. The script reads an ini file to determine if there is a blackout period for certain db's... ie: we don't care if it's up or down 1700 - 700 the next morning.

The ini file looks like:

<db_name>:<priority>:<blackout_start>:<blackout_end>

so

dbs1:H:17:07 (Where 17 is 5 PM and 07 is 7 AM)

Now I have code that looks like:

Code:

 
BLACKOUT_START=`grep -i "$ORACLE_SID" $INIFILE | cut -d":" -f3`
BLACKOUT_END=`grep -i "$ORACLE_SID" $INIFILE | cut -d":" -f4`
CURRENT_HOUR=`date +%H`
if [[ $CURRENT_HOUR -ge $BLACKOUT_START || $CURRENT_HOUR -lt $BLACKOUT_END ]]; then
   if [[ $CURRENT_HOUR -ge $BLACKOUT_START && $CURRENT_HOUR -lt $BLACKOUT_END ]]; then

I can't get my head around the logic to check for the conditions when the blackout end is less then the current hour and greater then the current hour and so on...

If Anyone has any suggestions or a cool blackout processing script that I could look at I would greatly appreciate it.

Thanks.

installsieve

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
