Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php $ php -r '$i = 0026; var_dump($i);' int(22) Previous Comments: ------------------------------------------------------------------------ [2009-07-17 17:26:47] satovey at yahoo dot com Description: ------------ When converting Gregorian date to Julian day and then back to the Gregorian date, unexpected results can occur if the year being two digits such as (26) is entered as a four digit (0026). This produces a four year difference of 1461 days. The quick solution to this is to enter four digit years such as 0026 as a literal '0026'. Reproduce code: --------------- $month=3; $day=18; $year=26; $gregToJd=gregoriantojd($month,$day,$year); $gregDateFromJd=JdToGregorian($gregToJd); echo "month: $month, day: $day, year: $year <br>"; echo "JulianDay from gregorian date: $gregToJd <br>"; echo "GregorianDate from julian day: $gregDateFromJd <br>"; $month=3; $day=18; $year=0026; $gregToJd=gregoriantojd($month,$day,$year); $gregDateFromJd=JdToGregorian($gregToJd); echo "month: $month, day: $day, year: $year <br>"; echo "JulianDay from gregorian date: $gregToJd <br>"; echo "GregorianDate from julian day: $gregDateFromJd <br>"; $month=3; $day=18; $year='0026'; $gregToJd=gregoriantojd($month,$day,$year); $gregDateFromJd=JdToGregorian($gregToJd); echo "month: $month, day: $day, year: $year <br>"; echo "JulianDay from gregorian date: $gregToJd <br>"; echo "GregorianDate from julian day: $gregDateFromJd <br>"; Expected result: ---------------- One would expect the following output from the code: month: 3, day: 18, year: 26 JulianDay from gregorian date: 1730633 GregorianDate from julian day: 3/18/26 month: 3, day: 18, year: 22 JulianDay from gregorian date: 1730633 GregorianDate from julian day: 3/18/26 month: 3, day: 18, year: 0026 JulianDay from gregorian date: 1730633 GregorianDate from julian day: 3/18/26 Actual result: -------------- The actual output of the code is as follows: month: 3, day: 18, year: 26 JulianDay from gregorian date: 1730633 GregorianDate from julian day: 3/18/26 month: 3, day: 18, year: 22 JulianDay from gregorian date: 1729172 GregorianDate from julian day: 3/18/22 month: 3, day: 18, year: 0026 JulianDay from gregorian date: 1730633 GregorianDate from julian day: 3/18/26 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=48963&edit=1
