Date stuff

[NeoGeo]

If I have a timestamp is there a way to subtract 30 days and get a new timestamp that is 30 days older?

So something like this: (psuedo-code)

$timestamp1 = TIMESTAMP;
$date1 = ConvertTStoText($timestamp2);

echo $date1;

$timestamp2 = $timestamp1 - 30days
$date2 = ConvertTStoText($timestamp2);

echo $date2;

===================

If $date1 is "April 1st 2003" than I would want $date2 to be "March 3rd 2003"

Thanks,
Ben

The key is to store your dates and times together as an integer. Then use php to do the calculations. It is WAY easier that way. The mysql date functions look pretty in the tables, but who cares? You have to convert the damn things to integers everytime you want to perform a date calculation anyhow...

For your problem you would just find out how many seconds are in 30 days. (60x60x24x30=2592000seconds). Then take your current date, (as an integer), and add the plus 30 days in seconds:

$now = time();
$thirty_days_from_now = $now + 2592000;

Then you can use the date() function to display it however you like with php.

Works perfectly.
