It seems these code paths are well tested and work fine.I've seen quite a few people that for whatever reason insist on running systems in local time zones struggle with the DST reverse step. It's not nearly as much of a non-issue as you claim.
Read again, and note the word "us". I am describing my and my employer's experience with past DST changes and leap years, and those have indeed been completely uneventful. YMMV.
The leap second in 2012 however ... total and utter carnage. Application servers, databases, etc. falling over like dominoes. All hands on deck in the middle of the night to clean up. It took days before we stopped finding broken stuff."Total and utter carnage" is a bit of a stretch.
As above, I am speaking only about how the 2012 leap second went down in our infrastructure. I stand by how I described the event. Again, YMMV. If you plan on let your infrastructure deal with the upcoming leap second head-on, I wish you the best of luck. Hopefully all the bugs from 2012 have been fixed. I, however, certainly have no intention of being the one to find out otherwise. Tore
