(PHP 3 >= 3.0.7, PHP 4, PHP 5)
gettimeofday -- Get current time
Description
mixed 
gettimeofday ( [bool return_float] )
   This is an interface to gettimeofday(2). It returns an
   associative array containing the data returned from the system
   call.
  
   Since PHP 5.1.0 there is an optional parameter,
   return_float, which makes
   gettimeofday() return a float when it is set to
   TRUE.
  
   Array keys:
   
      "sec" - seconds since the Unix Epoch
     
      "usec" - microseconds
     
      "minuteswest" - minutes west of Greenwich
     
      "dsttime" - type of dst correction
     
  
   
Example 1. gettimeofday() example 
<?php print_r(gettimeofday());
  echo gettimeofday(true); ?>
 |  
 The above example will output 
something similar to: Array
(
    [sec] => 1073504408
    [usec] => 238215
    [minuteswest] => 0
    [dsttime] => 1
)
