I know you've satisfied yourself that things are okay, but I need to point
out an incorrect comment in your message (if only to satisfy the pedant in
me). date(1) will, in fact, permit you to specify a 4-digit date. I quote
from the man page:
-f Use fmt as the format string to parse the date provided rather
than using the default [[[[yy]mm]dd]HH]MM[.ss] format. Parsing
is done using strptime(3).
strptime(3) is to strftime(3) as scanf(3) is to printf(3): That is,
strptime() will parse a date string using the '%' escapes recognized by
strftime(). (If I recall, strptime() is an X/Open-specified routine.)
For example:
(current) ~ > sudo date -f '%Y' 2001
