bug#9241: Gnus dynamic "Date:" should not update every second

[Stefan Monnier]

,gnusThe dynamic update of relative time on the "Date:" line in the article
buffer is annoying.  Mentioning seconds is largely pointless, and
updating every second is a real problem (e.g. it keeps Emacs busy,
preventing it from being swapped out).  It even occasionally causes
the display to "flicker" because at times the "Date:" line needs
wrapping and at times it doesn't.

I'd be happy to turn off the "feature" altogether, but at least by
default the updates should not take place every second.  If some user
really likes it, then feel free to keep it as an option
"gnus-update-date-obnoxiously", and maybe even provide a sub-second
version "gnus-update-date-for-masochistic-epileptics", of course.
