Hi!
We've come across a problem in an upgrade of Nagios 3 to Nagios 4 which =
we can't work out where the fix is. It occurs when an event is scheduled =
in the future beyond 2038.
Recreation steps:
* Set a downtime on a service to end next day
* Stop Nagios
* Edit the retention.dat so that the end_date=3D4514791088 (some other =
values seem to work)
* Start Nagios
When Nagios starts, it will not run any scheduled events in the events =
queue.
This fails on CentOS 5 64bit, though appears to work on Debian Squeeze =
32bit, so it maybe a 64 bit only issue.
We think this is an issue when the event is scheduled via squeue_add(). =
We've managed to get the test-squeue to fail by changing the time value =
to be greater than 2038 with the following:

This gives the test result of:

about to fail pretty fucking hard...

Changing to a factor of 1.1 instead of 2 passes:
### squeue tests
Test results: 390647 passed, 0 failed
This worked in Nagios 3, so we're guessing that the change to use the =
squeue library for events is probably where this limitation has come in.
Any thoughts?
