Calendar · views on the clock keep moving

The week and day views read the clock once and handed that moment down
as given, which turned off the line's ticker: the line at now and the
lit day stood still. The owner's moment now goes down unchanged, and a
time grid, month view or year view on the clock keeps its own ticker,
so the line moves and today turns over at midnight, even on days that
are not today. A given moment holds them still.
