Hello,

i've written a daemon in php and everthing works fine.
i'm able to execute tasks periodically. for example every 900 seconds.

now i want the daemon to do a task only once a day,
for example at 1800 hours. but i'm not sure how to do
this.
saying something like

while (true)
{
if ($current_time==1800) dosomething
}

fails if i miss 1800 exactly.
saying something like

while(true)
{
if ($current_time<=1801 && $current_time=>1800) dosomething
}

leads to running the function twice, or more depending on
the execution time of the function.

I'm using php 4.3 (more is not allowed at the moment)

Thanks for any help....

Greetings, Dirk
