[suspicious - maybe spam] Re: Help with dates

Check out: http://pear.php.net/package/Date According to the description, it lets you compare dates that date pre 1970 and post 2038. /Mattias (If I could only get off ezmlm's "suspicious user list". I think there isn't much I can do, it's my ISP rejecting some PHP list postings.) Kevin wrote:

Greetings Mr Mattias, I wish it was so simple. Because the dates that may need calculating can be before 1970. THis function I have.. and it's semi-working, but I've noticed irregularities during the conversion. Thanks for your suggestion!!

well, you can simply use the unix timestamp, since the amount of days / seconds since 0 AD/BC will be a constant (it won't change, trust me), you can simply add it to that, and add a wrapper function to php's time(). You'll be working with VERY big numbers in that case, so you can also do it the other way around; store the amount of DAYS since 0 AD/BC till Jan 1st 1970, add time()/86400, and you'll have the amount of days since 0 AD/BC in an integer (or float, depending on how many days that really are). You'll just need to find that constant somewhere :)

Can't be too hard to calculate it: 1970 * 365 + 1 day for each leap year. Note the rules for leap year, of course. /Mattias -- More views at http://www.thorslund.us
