TimeMachine

TimeMachine (TimeZone/Time Conversion Manager)

Time Machine can be used as follows:

$timeMac=new TimeMachine(); //Instantiate Time Machine

Set TimeZone
Time Machine can be set to $timeMac->setTZ("Australia/Sydney");or $timeMac->setTZ("Australia/Brisbane");with no problem. But when a non existant timezone is specified it will throw an error ie $timeMac->setTZ("Hogwarts");
A list of valid timezones can be found at http://www.php.net/manual/en/timezones.php

Get TimeZone
$timezone=$timeMac->getTZ(); (or $timezone=$timeMac->getTZ("basic");)
echo $timezone;
Would return the current timezone
Example: Australia/Sydney

$TIMEZONE=$timeMac->getTZ("full");
die("<pre>".print_r($TIMEZONE,true)."</pre>");

would return an array of the current timezone and is Daylight time is active or not

Example:

Array
(
    [timezone] => Australia/Sydney
    [dstactive] => 1
)

or

Array
(
    [timezone] => Australia/Brisbane
    [dstactive] => 0
)

List All TimeZones

An array can be populated with a list of timezones in the Country/City Format as shown below

Example:
$RETURN=$timeMac->getTimeZones('basic');

RETURNS:

Array
(
    [0] => Africa/Abidjan
    [1] => Africa/Accra
    [2] => Africa/Addis_Ababa
    [3] => Africa/Algiers
    [4] => Africa/Asmara
    [5] => Africa/Bamako
    [6] => Africa/Bangui
    [7] => Africa/Banjul
    [8] => Africa/Bissau
    [9] => Africa/Blantyre
    [10] => Africa/Brazzaville
    [11] => Africa/Bujumbura
    [12] => Africa/Cairo
    [13] => Africa/Casablanca
    [14] => Africa/Ceuta
    [15] => Africa/Conakry
    [16] => Africa/Dakar
    ...

Example 2:
$RETURN=$timeMac->getTimeZones('full');

RETURNS:

Array
(
    [Africa] => Array
        (
            [0] => Abidjan
            [1] => Accra
            [2] => Addis_Ababa
            [3] => Algiers
            [4] => Asmara
            [5] => Bamako
            [6] => Bangui
            [7] => Banjul
            ...
        )

    [America] => Array
        (
            [0] => Adak
            [1] => Anchorage
            [2] => Anguilla
            ...

Example 3:
$RETURN=$timeMac->getTimeZones('countries');

RETURNS:

Array
(
    [0] => Africa
    [1] => America
    [2] => Antarctica
    [3] => Arctic
    [4] => Asia
    [5] => Atlantic
    [6] => Australia
    [7] => Europe
    [8] => Indian
    [9] => Pacific
    [10] => UTC
)

Time Conversion

Can be used to convert times between TimeZones.

Example 1:

$sourcetime="2000-01-01 17:30:00";
$RETURN=$timeMac->timeZoneConvert($sourcetime, "Australia/Sydney", "UTC");

RETURNS:
2000-01-01 06:30:00

Example 2:

$sourcetime=date("Y-m-d H:i:s");
$RETURN=$timeMac->timeZoneConvert($sourcetime, "Australia/Sydney", "America/New_York");

RETURNS:
2017-02-25 10:28:14
