#21646 [NEW]: Strftime: negative timestamps
From: [EMAIL PROTECTED] Operating system: all PHP version: 4.3.0 PHP Bug Type: Feature/Change Request Bug description: Strftime: negative timestamps Situation: The function strftime does return false for negative unix-timestamps. Problem: The functions mktime and strtotime return negative values for dates before 1970-01-01 00:00 UT. Many users try something like: strftime($format,strtotime($date_before_1970)) and wonder why this does not work. If the behavior for timestamps before second 0 (start of Jan 1., 1970 UT) is undefined why do all other time functions return negative values ? The documentation for strftime does not say anything about negative values for timestamps, too. Solution: Let strftime return values (Gregorian calendar) for negative timestamps.
