The problem is how you look at it:
mktime first calculates year + month...
the last step is to add the seconds.
I wanted this the other way round. Would be a nice feature to select the priority of
the different input values. When you use unix timestamps for calculations its very
difficult to add 1 year (or something similar) to that date...

first of all:
I use php 4.0.1pl2 and don't have the possibility to upgrade. Please verify with
latest version.
I tried to add 12 months to a given timestamp and figured out that mktime() doesn't
include a 29th February into its calculations. Effect is, that following code doesn't
jump forward 1 year during each loop. Every leap year 1 day gets lost!
$a = mktime(0,0,0,1,1,1970);
for ($i=0; $i<20; $i++) {
$a = mktime(0,0,3600 +$a,1+12,1,1970);
$b = date("d-m-Y", $a);
print "Date: $b";
}
