Date.php and Calc.php Updates

Hi All, First time contributing to Open Source so... I have some updates to the Date package in PEAR, the changes have been done on the latest files from cvs.php.net / pear / Date as of 04-FEB-2003 GMT and can be downloaded from http://www.mistral-networks.co.uk/dl/pearDate.zip I've added one file test/test_date.php which is the start of a test script to put the Date package through it's paces. I've updated two files Date.php and Date/Calc.php A summary of changes are below. I guess not everyone will want the UK, EURO and US date support in there (I do) but there are other valuable additions. Calc.php ======== Modified function defaultCentury to handle years of 1, 2, or 3 digits long e.g. given a year of 512 the old version produced 19512, new version returns 0512 given a year of 2000 the old version produced 192000, new version returns 2000 given a 2 digit year, behaviour as per previous version Added functions addDays and subtractDays Similar to nextDay and prevDay but adds an arbitary number of days instead of just one. Allows calcs like what is the date 57 days from now or Password Expiry Date is today plus 32 days. Date.php ======== Added support for UK Dates (DD/MM/YYYY HH:MM:SS) EURO Dates (DD-MM-YYYY HH:MM:SS) US Dates (MM-DD-YYYY HH:MM:SS) new constants for above are DATE_FORMAT_EURO DATE_FORMAT_UK DATE_FORMAT_US (maybe should be NORTHAMERICA or AMERICAS?) Added Functions isValidDate - wrapper for Date_Calc::isValidDate getFutureDate - wrapper for Date_Calc::addDays getPastDate - wrapper for Date_Calc::subtractDays Several bits to handle badly formed years in dates (1,2, or 3 digit years) magicCentury - wrapper for Date_Calc::defaultCentury setMagicCenturyFlag - Set flag to turn on/off use of magicCentury function getMagicCenturyFlag - get current magicCentury Setting Constants for magicCentury Handling OFF ON New Class Property (flag for magic Century) var $magicCentury; Constructor altered to set magicCentury off by default ensures backwards compatibility function setDate Detects whether or not to run $this->year property through magicCentury or not Feel free to comment and / or alter the code Regards Dean Urmson Mistral Networks Management Ltd (please ignore the out of date website)
