Yes, it is "Darwin" specific.
It is enough to use MacOS X 10.0.0 to 10.0.3 (MacOS X
Server is not need!)
OR
you can use Darwin/Intel (see: http://www.darwinfo.de), if
you don't have a Apple Macintosh.
I used this patch for some weeks and an more primitiv patch
some month. It works well and it can test on all other
platforms you have. I will made some more test with some
bigger values for each field...
Whats the problem? You are using an undocumented feature
and all other UNIX work in the same way. But it is not
safe!

MacOS specific. Not critical untill we can find some MacOS X servers for developers/QA
Team to test on.

see Bug id #8828, too!
On PHP documantation:
mktime(hour,min,sec, year,0,mon) refers the last day of month 'mon-1'. On MacOS X this
failed, there it refers the first day of month 'mon' and mktime(hour,min,sec,
year,-1,mon) refers the last day of month 'mon-1'.
On MacOS X 10.0.2 (Darwin 1.3):
02.03 --> 983487600 --> 02.03
01.03 --> 983401200 --> 01.03
00.03 --> 983401200 --> 01.03
-1.03 --> 983314800 --> 28.02
-2.03 --> 983228400 --> 27.02
i have check some UNIX-systems and i haven't found any man-page, where is describe
what should be happend on "tm_mday" <= 0. The problem is happend on all values out of
bounds, when using mktime()!
IMHO this is a undocumented feature, which is used by PHP.
man mktime (Linux 2.2.13)
tm_mday The day of the month, in the range 1 to 31.
Sun Release 4.1
int tm_mday; /* day of month (1 - 31) */
SunOS 5.5
int tm_mday; /* day of the month - [1, 31] */
HP-UX Release 10.20
int tm_mday; /* day of month - [1,31] */
HP-UX Release 11.00
int tm_mday; /* day of month - [1,31] */
AIX 4.3.2
int tm_mday; /* Day of month (1 - 31) */
Darwin 1.0.2
int tm_mday; /* day of month (1 - 31) */
I think i should by much better to check mktime() on configure and set a #define for
compilation. Only on "datetime.c" must be made a patch to support MacOS X's / Darwin's
mktime()-systemcall, i think!
Patch to make php_mktime() more compatible [i think it is not complete for the whole
PHP4-project]. It includes a time correction for values less then 1 on "mday",
"hour", "min", "sec", "mon"!!
