BUG/MINOR: clock: fix a few occurrences of 'now' being used in place of 'date'

Since commit 28360dc ("MEDIUM: clock: force internal time to wrap early
after boot") we have a much clearer distinction between 'now' (the internal,
drifting clock) and 'date' (the wall clock time). There were still a few
places where 'now' was being used for human consumption.

No backport is needed.
