TimeStamp Standard PHP

I am working on creating a log file where log details including timestamp should be written to the log file. But is there any standard timestamp function which I can use in the php code which does not show any s开发者_运维百科ort of errors like "You cannot rely on SYstem's timezone' etc . Thanks

You could try this:

date_default_timezone_set('GMT');
$stamp = time();

See date_default_timezone_set(..) to get rid of that error.

Otherwise use time() and date(..).
