Not sure any laws were passed on Feb 30th 1712 in sweden, but perhaps
you can define new time zones to handle that, but I doubt it is practically
doable when you get to countries and regions with less precise boundaries.

Seconds-since as a representation for dates is a dangerous and very
messy game. Java gets it wrong somewhere in 1910 and my guess is others
get it wrong too. There is change in time zones which triggers the bug.
