Daylight saving time and Timezone best practices

Basically I have the following problem:

I have a table with all the GMT offsets and based on that I calculated the users hour relative to the servers hour but some are off by an hour.

So my function looks like this, it takes GMT+/-3600*usersTZ(GMT offset). London looks ok, Australia looks ok, but hey Samoa, instead of being eg: 5 it`s 6.

I figured that might be the case with daylight saving, any ideeas?

PHP can handle timezones natively. You just need to set timezone in olson format like America/New_York.

You can then use date_default_timezone_set or any other php DateTime stuff that understands timezones.

It would be very helpful to peruse the PHP docs a little. Especially here and here.
