problem with dates

[BODEKA]

I am having poblem with dates.


When I run the following code how come I get
$today-$yesterday: 25 hours

and

$tomorrow-$today: 24 hours
--------------------------------
<?php

$now = time();

$today    = mktime(0, 0, 0, date("m", $now)  , date("d", $now),  date("Y", $now));
$yesterday = mktime(0, 0, 0, date("m", $now)  , date("d", $now)-1, date("Y", $now));
$tomorrow  = mktime(0, 0, 0, date("m", $now)  , date("d", $now)+1, date("Y", $now));


echo "today-yesterday: ".($today-$yesterday)/$hour." hours"."<br />";
echo "tomorrow-today: ".($tomorrow-$today)/$hour." hours"."<br />";

?>

Not sure what it is you're trying to do but...try this to get you started:

[code]<?php

$today = time();
$yesterday = ($today - 86400);
$diference = (($today - $yesterday) / 60) / 60;

print_r($diference);

?>[/code]

Maybe if you explained what you're trying to do...?

How come one deduction gives me 24 hours difference as I expect it to be
but the other one gives me 25 hours difference.

I forgot: $hour = 3600;

If you're in the US, yesterday, October 29th, had 25 hours due to the switch from Daylight Saving to Standard time.

Thanks Ken, I completely forgot about time switch.
