Error reported by Duncan Smith <dds@…>:

There is a 30 day error in _TOD_Days_since_last_leap_year[2..3]

Thanks.
What's the condition to hit this error?
Every year 4n+2 and 4n+3 ?
(i.e. 1998, 1999, 2002, 2003, ...)

OK: 96 97 00 01 04 05 ...
Bad: 98 99 02 03 06 07 ...

There is also a problem in newlib 1.7.x reported at the same time:

I found another, that would strike only on 2/29/2000, or other leapyears.
Only a problem on 1 day.

Joel: FYI, there is a bug in Newlib localtime.c, localtime or (_tm_time).
Ours is modified for dst and timezones, but the bug was in original source.
I have not looked at the latest public source (nor do I know where to find
it).
