>Description:
Reading localtime.c, it really looks to me as though 'isleap()' (the macro
for detecting leap years) is being called on the 'tm_year' structure member.
Unfortunately, that's off by 1900 for the '%400' test.

>How-To-Repeat:
Read the code.
>Fix:
Double-check this, and possibly add '+1900' to the %400 check.
