Use a hash as a state table.

You'll have to fill in how you get your 0s and 1s and concatenate them, and getting your times into comparable format (seconds since...).

#! perl -slw
use strict;

my %states = (
    0000 => 1, 0001 => 0, 0010 => 0, 0011 => 0,
    0100 => 0, 0101 => 0, 0110 => 0, 0111 => 0,
    1000 => 1, 1001 => 0, 1010 => 1, 1011 => 0,
    1100 => 1, 1101 => 0, 1110 => 0, 1111 => 1,
);

my $state = ....; ## Get state from wherever?

if( $states{ $state } ) {
    ## Validate values
    my( $startTime, $endTime ) = ...; ## Get times
    if( $startTime < $endTime ) {
        ## Do it
    }
    else {
        ## Reject.
    }
else {
    ## Reject.
}

BTB. If specifying just start and end hour is valid, why isn't specifying start hr/min and just end hr (1110) also valid? Eg. Start:10:45 * End: 11
