Unrecognized characters in the format string will be printed as-is. The "Z" format will always return "0" when using gmdate().

Example 1. Date() example
      1
      2 print (date ("l dS of F Y h:i:s A"));
      3 print ("July 1, 2000 is on a " . date ("l", mktime(0,0,0,7,1,2000)));
      4

It is possible to use date() and mktime() together to find dates in the future or the past.

Example 2. Date() and mktime() example
      1
      2 $tomorrow  = mktime (0,0,0,date("m")  ,date("d")+1,date("Y"));
      3 $lastmonth = mktime (0,0,0,date("m")-1,date("d"),  date("Y"));
      4 $nextyear  = mktime (0,0,0,date("m"),  date("d"),  date("Y")+1);
      5

To format dates in other languages, you should use the setlocale() and strftime() functions.
