Absolute timers that expire at midnight UTC may fire one second early when the leap second is inserted.
Impact to applications unknown. The system stays stable, and a timer may be fired off earlier than expected
This occurs if an absolute timer is used to trigger a task, and the leap second occurs during the timer window. For example if an absolute timer of 60 seconds is scheduled and the leap second event occurs midway through that interval, the event will appear to fire one second earlier than expected.
