Bug #13880: date(I) does not correctly identify daylight saving time

From: bmplummer1@home.com Operating system: Windows NT/XP PHP version: 4.0.6 PHP Bug Type: Date/time related Bug description: date(I) does not correctly identify daylight saving time There appears to be a bug in the date() function when using the I (capital i) format. Date(I) always returns 0 (zero) no matter what the date is. Date(I) is used to determin if a date occurs during daylight saving time or not. Here is the script I am using: if (date(I, mktime(0,0,0,6,1,2001))=1) { do this; } else { do that; } No mater what the date is it always returns zero. I have tried setting date(I) to a variable outside of the if/then statement but it always sets the variable to zero. I have tried setting the timestamp to a variable first and using it in date(): $ts = mktime(0,0,0,6,1,2001); $ds = date(I, $ts); That doesn't work either, returns zero. No matter what I do it just doesn't work. Does this part of date() even work? Running PHP 4.05 with Zend Optimizer v1.1.0 on Windows NT 4.0 build 1381, CGI version, Apache/1.3.20 . Also doesn't work on PHP 4.06 on Windows XP, CGI version, Apache/1.3.22. Thank you for your consideration and hard work. PHP is a great product. Keep up the good work!
