FactSpan built both instants by adding a duration to local midnight, so on
the two DST changeover days every span was an hour off. A day is 23 or 25
hours wide there, and the busy gate then read a 14:00 meeting as 13:00 or
15:00. Both readings are time.Date now, and the midnight crossing is AddDate
rather than a 24-hour add.
The iCal parse did not unfold content lines. A server folds a property at 75
octets and a Russian summary is two bytes a letter, so the tail of an
ordinary weekly standup was read as an unknown property and dropped, and the
event was filed under a truncated name. RFC 5545 TEXT escapes are also
reversed now, which RenderICal has always written and the parse never undid.
Two regression tests: a folded and escaped summary, and a span across the
start of DST in Europe/Berlin.
