Description:
------------
Documentation of mktime's year parameter states that

> The number of the year, may be a two or four digit value,
> with values between 0-69 mapping to 2000-2069 and
> 70-100 to 1970-2000. 

But this part, `70-100 to 1970-2000`, is not precise.

As in the implementation in ext/date/php_date.c::php_mktime,
the doc should read:
"70-110 to 1970-2010", instead of, "70-100 to 1970-2000".


Reproduce code:
---------------
echo date("Y-m-d", mktime(0,0,0,1,1,110));

Actual result:
--------------
2010-01-01

Thank you for the report, and for helping us make PHP better.

The documentation was changed to reflect this "issue". It looks like 
mktime is not actually the culprit here but the timelib/tm2unixtime 
code.
