# gettimeofday

(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

範例 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
    )

    1073504408.23910
