timestamp confusion

hi, when people add something to a table, i'm logging the time()... later, when I pull it out, i'm doing something like date('d M Y',$stamp), which all works fine, printing something like "21 Jan 2002". problem is, i'm on a server in canada, but 99% of my users will be in Australia. to get an idea of the time difference, I made a simple php file called time on both my local test server and the live server: <? $stamp = time(); echo $stamp."<BR>"; echo date('d M Y H:m:s', $stamp); ?> I ran both scripts within 5 seconds of each other, and got the following: local: 1014261839 21 Feb 2002 14:02:59 live: 1014260440 20 Feb 2002 21:02:40 So, if I look at the second line of the output, they're about 17 hours behind me, but if I look at the first line [time()] (according to the manual, the number of seconds since that date in 1970 i think), I get a way different result: 1014261839 - 1014260440 = 1399 seconds difference, about 23 minutes. I want to be able to determine the $difference between the two stamps in seconds, then do something like: <? echo date('d M Y',$stamp - $difference); ?> Seems easy enough, but 1399 doesn't seem right to me!!!!! Where have I lost the plot??? Justin French http://indent.com.au http://soundpimps.com
