Calculating tim - easy for you! =)

Hello out there in the jungle...
=)

I found out that i can calculate the dates e.g

$today = strftime('%Y%m%d',mktime(0, 0, 0, date("m"), date("d"),
date("Y")));
$yesterday = strftime('%Y%m%d',mktime(0, 0, 0, date("m"), date("d") - 1,
date("Y")));
$dayBeforeYesterday = strftime('%Y%m%d',mktime(0, 0, 0, date("m"),
date("d") - 2, date("Y")));
$dayBeforeTheDayBeforeYesterday = strftime('%Y%m%d',mktime(0, 0, 0,
date("m"), date("d") - 2, date("Y")));

and so on........

This works even if we have the 1st of August $yesterday gives me the 31st
july.

Can I do this with times also??

e.g. Iit it now 17:06 an i want to make minus 20 min (like abopve minus 1
day) and I want the result to be 16:46.
I tried the above example, wit %H%M but it does not work?

Any ideas?

Thanks

Yes, it does :)

$a_little_while_ago = strftime('%Y%m%d %H%M', mktime(date('H'),
date('i')-20, date('s'), date('m'), date('d'), date('y')));

Unix timestamps are in general easier to work with as they're just numbers:

define(SECONDS_IN_A_DAY, 60 * 60 * 24);

$now = time();
$today = date("Y m d", $now);
$yesterday = date("Y m d", $now - SECONDS_IN_A_DAY);
$dayBeforeYesterday = date("Y m d", $now - SECONDS_IN_A_DAY * 2);
$dayBeforeTheDayBeforeYesterday = date("Y m d", $now - SECONDS_IN_A_DAY *
3);
