If anybody (derick?) cares,
gmmktime returning completly bogus results. It can be easly checked out
by manually setting TZ shell variable.
Lets try it like this:
TZ=GMT+1 php -r "echo gmmktime();"
gives 1100292805
TZ=GMT+2 php -r "echo gmmktime();"
gives 1100289207
TZ=GMT+3 php -r "echo gmmktime();"
gives 1100285610
But it should return always the same time (ok, few seconds here and
there, needed to type each command..) no matter which timezone is set.
Why ? Because 'tm_gmtoff' (and gmadjust manually calculated from
'timezone' and 'is_dst' in cases where tm_gmtoff is not available) shows
number of seconds EAST from GMT (man localtime is your friend here). So
to get GMT time from, we have to _substract_ this number from localtime,
and what is php currently doing, is adding it to localtime, which can't
be a good thing no matter how you look at it (-:
