Timezone code produces E_STRICT/E_WARNING
If PHP version supports Auto-DST and new TZ features, but user disables Auto-DST, all datetime functions in plugin function called via callback, TXP’s commenting system etc will produce errors. Let’s give small code example:
register_callback('timezone_test','textpattern_end');
/**
Small testing function. Calls datetime function.
*/
function timezone_test() {
echo
safe_strftime('%Y');
}Results:
Strict Standards: getdate() [function.getdate]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Helsinki' for '3.0/DST' instead in C:\xampp\htdocs\developement\rah\textpattern\lib\txplib_misc.php on line 1262
Strict Standards: mktime() [function.mktime]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Helsinki' for '3.0/DST' instead in C:\xampp\htdocs\developement\rah\textpattern\lib\txplib_misc.php on line 1263
Strict Standards: Non-static method timezone::is_dst() should not be called statically in C:\xampp\htdocs\developement\rah\textpattern\lib\txplib_misc.php on line 1265
Strict Standards: strftime() [function.strftime]: It is not safe to rely on the system's timezone settings. Please use the date.timezone setting, the TZ environment variable or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'Europe/Helsinki' for '3.0/DST' instead in C:\xampp\htdocs\developement\rah\textpattern\lib\txplib_misc.php on line 1299Following conditions must be met:
- PHP 5.1.0+
- Site must be in Live mode. Testing and debugging won’t return E_STRICT.
- Auto-DST must be disabled. Will result in commenting fails too which is ‘fixed’ in SVN (supressed).
This happens on various servers when Auto-DST is disabled. There are quite many threads about the issue over the forums, and posts in plugin threads.
Current workaround:
- Using SVN build which supresses errors.
- Setting Auto-DST on which fixes all other errors than timezone::is_dst()’s calling.

Re: Timezone code produces E_STRICT/E_WARNING
What’s your suggestion to deal with this inconsitency in PHP’s error reporting besides the mentioned fix?

If you say merely suppressing the errors is a fix, then I will say that forcing Auto-DST on (when supported) is a fix, because setting it on, removes the notices, except method timezone::is_dst() should not be called statically.
