 New Comment:

I'm not sure there would be consensus on my expected return values here,
but it 

makes more sense then getting March as a result.



Reproduce code:

---------------

date_default_timezone_set('America/New_York');

echo date(DATE_RFC822,strtotime('march 31 2010 -1 month'));

echo date(DATE_RFC822,strtotime('march 30 2010 -1 month'));

echo date(DATE_RFC822,strtotime('march 29 2010 -1 month'));

echo date(DATE_RFC822,strtotime('march 28 2010 -1 month'));





Expected result:

----------------

Sun, 28 Feb 10 00:00:00 -0500

Sun, 28 Feb 10 00:00:00 -0500

Sun, 28 Feb 10 00:00:00 -0500

Sun, 28 Feb 10 00:00:00 -0500





Actual result:

----------------

Wed, 03 Mar 10 00:00:00 -0500

Tue, 02 Mar 10 00:00:00 -0500

Mon, 01 Mar 10 00:00:00 -0500

Sun, 28 Feb 10 00:00:00 -0500

This may be fodder for another bug report, but strtotime() more
specifically 

"returns wrong results" for the last three days of March 2010.



date_default_timezone_set('America/New_York');

echo PHP_VERSION."\n".

  date(DATE_RFC822)."\n".

  date(DATE_RFC822,strtotime('last month'));

Re-opening because of the question marks:



firstdayof = 'first day of'?;

lastdayof = 'last day of'?;



It shouldn't cause an issue though, but it needs fixing.

Automatic comment from SVN on behalf of derick
Revision: http://svn.php.net/viewvc/?view=revision&revision=295892
Log: - Fixed bug #51096 ('last day' and 'first day' are handled
incorrectly when
  parsing date strings).
- For 5.2 I just added the test case minus new 5.3 additions.

Actually, there is a bug here "first day" and "last day" should be "+1
day" and "-1 day".
