I can relate:
My son is born at 02h30 right DST change time.
It tooks 3 f*cking days to get his birth registered in the Hospital new birth registration system.
The hospital (at the time) just got digitalized and most systems where not able to agree if he was born after or before DST changes.
PS: I guess he is born fated to be a software QA later on.
This commenter says he has different birth dates in different countries' sytems, which is correct if you consider the exact time of birth, but... that's probably a bug? https://news.ycombinator.com/item?id=48853128
