Tested for leap seconds?

There is a planned Leap Second to occur at midnight on 31st December 2016. We have previously had customers encounter erroneous offline license expiry issues relating to clock changes (for instance, due to daylight savings time) - has LimeLM been tested against leap second changes? Is there anything we can have our customers do to prepare for this time change if they've previously seen issues when the clock changes?

Thanks,Ian
