So, to clarify, you want a long running program to start running at 7pm, and put itself to sleep at 7am.
I would look at the sleep and localtime functions. Pay particular attention to the return value of the sleep function.

You could use an event loop, like this Glib example..... the trick is to return 0 or 1 to keep the timer going or to stop it. You could get very creative , depending on what code you need to run..... just fork and exec your code off, and let the timer do the checking for 7 to 7 in time.
#!/usr/bin/perl
use warnings;
use strict;
use Glib;
my $main_loop = Glib::MainLoop->new;
my $count = 1;
my $timer = Glib::Timeout->add (1000, \&timer_callback, undef, 1 );
#1000 milliseconds = 1 second
sub timer_callback{
$count++;
# are we between 7 and 7?.... if so....(code left up to you)
print "$count\n";
return 1; #return 1 to keep going, return 0 to stop timer
}
my $count1 = 1;
my $timer1 = Glib::Timeout->add (100, \&timer1_callback, undef, 1 );
sub timer1_callback{
$count1++;
print "\t$count1\n";
return 1;
}
### filehandle watch
#open (FH, "+> test.log") or warn "$!\n";
#Glib::IO->add_watch (fileno 'FH', ['in'], \&watch_callback, 'FH', 1 )
+;
$main_loop->run;

What's a program function? What kind of program are we talking about - is it running all the time, started on demand, ... ? Should the "program function" abort if the clock passes 7AM and it's still running? Or perhaps it should wait till 7PM? Why aren't you just checking the current time? | [reply] |
No it shouldn't abort because I want it to continue again when the time slot starts the next day.

Could you be a bit more elaborate on what it is what you want?
