+// * As per ISO 8601:2004 4.3.2.1, all dates follow the Proleptic Gregorian
+// calendar. As such, the day before 1582-10-15 is 1582-10-14, not 1582-10-04.
+// See: https://en.wikipedia.org/wiki/Proleptic_Gregorian_calendar
+// * As per ISO 8601:2004 3.4.2 and 4.1.2.4, the year before 1 AD (aka 1 BC)
+// is number "0", with the year before that (2 BC) being "-1", etc.
+// Conversion methods assume "the same timezone", and do not handle DST.
+// Leap seconds are not handled, they must be done manually if desired.
+// Suffixes such as "Z" are not handled, you need to strip them away manually.
