On June 30 2012, an extra second will be added to UTC, which will result in events with a timestamp of 'Jun 30 23:59:60' - Will Splunk recognize this as a valid timestamp?
I have multiline event log files that are broken based on the timestamp in the events, will Splunk still break the events properly?
If you are breaking events based on timestamps, that extraction should still work as the format of the timestamp will not change and that is what the linebreaking processor is interested in. What that timestamp actually means in real terms is not a consideration when identifying where to break events.
Any events containing the timestamp with a leap second will be indexed as 23:59:59, and will be searchable.
There is an interesting wiki about the leap second at https://en.wikipedia.org/wiki/Leap_second, for those curious to better understand.
