The documentation tells one that the year position in the list output by
localtime is actual year - 100, not a two-digit year.

The documentation also, I think, tells one that in sprintf and friends, the
specification %02d says to use *at least* two digits to represent the
number and to zero fill if there is only one digit.  If there are 6 digits
(unlikely for years) they will appear.

  --John (who long has said that while Unix provides the tools to handle
Y2K properly (Y2038 is another matter), it's still possible to produce
results which have Y2K problems by misusing the tools Unix provides.
Actually, I mostly said that about MacOS)
