I located the source of the problem. The day and hours aren't
displaying because the themeinfo.php files still contain %e for
the day and %l for the hours. If you change the %e to %d and %l
(small L) to %I (capital i), then it works fine on IIS. Small L
isn't on the list of recognized specifiers. I'm surprised that
one works for anyone.
For your records, IIS recognizes all specifiers for the date
function. It does NOT recognize these for strftime: %C, %D, %e,
%g, %G, %h, %n, %r,%R, %t, %T, %u, and %V. Recommend a comment be
added to the documentation telling IIS users to avoid them. The
other ones work okay.
On a different subject, the graphics for phpwiki look very
professionally done. But...yes, I'm inserting a but here....some
(not all) have a gray border around them in IE 6. They look great
in NS 6, NS 4.7, and Opera 6 but IE doesn't render some of them
correctly. I'm bringing this up because IE is the predominantly
used browser today. About 90% of the people use it. Whatever the
difference is now this browser doesn't like it.
