It goes by your machine's clock. Yes, it is. UNIX timestamps are *always* in GMT -- here is the definition from the PHP time() page: > Returns the current time measured in the number of seconds since > the Unix Epoch (January 1 1970 00:00:00 GMT). Note that GMT on the end. Believe me, I have researched this extensively -- you will find that the same timestamp represents all these times: 12:00 1-Dec-2004 GMT (London, England) 07:00 1-Dec-2004 -0500 (New York) 20:30 1-Dec-2004 +0830 (Darwin, Australia) and so on. It is date() and mktime() that do the conversion to and from the server's local timezone, including DST adjustments where necessary. The timestamp is timezone agnostic. Cheers!
