Đôi lúc các bạn xem các hướng dẫn về hàm lấy thời gian :date[format,timestamp].
Nếu chưa biết hàm date[format,timestamp] bạn có thể xem ở link://congnghe5s.com/bai-viet/xu-ly-ngay-gio-trong-php.html.
Bạn thực hiện test lệnh trên máy và kết quả không khớp với time hiện tại. Đó là vì lí do thời gian hay timezone trên server bạn đã cài đặt khác vì thế để trả về đúng time bạn muốn bạn có thể dùng hàm:
Cú pháp:date_default_timezone_set [ string $timezone_identifier ].
tham số : $timezone_identifier bạn lấy ở đây://php.net/manual/en/timezones.asia.php
phù hợp khu vực bạn muốn ví dụ mình muốn set lấy giờ việt nam mình làm như sau:
date_default_timezone_set['Asia/Ho_Chi_Minh'].
Sau đó các bạn dùng hàm : echo date['d/m/Y - H:i:s'];
ra đúng kết quả time ở Việt Nam.
Ví dụ:
date_default_timezone_set['Asia/Ho_Chi_Minh']; if [date_default_timezone_get[]] { echo 'date_default_timezone_set: ' . date_default_timezone_get[] . ' '; } echo date['d/m/Y H:i:s'];Ví dụ trên có 1 hàm cũng khá quan trọng : date_default_timezone_get[] trả về timezone mặc định của server bạn đang chạy hoặc là đã được thiết lập thông qua date_default_timezone_set[].
Qua bài viết hy vọng các bạn có thêm kiến thức khi xử lý ngày tháng trong PHP.

i want to know how is possible to add a time offset or subtract it this way.
// stored values of states and its column.
"NT" = +9.30
"QLD" = +10.00
"WA" = +8.00
i am taking selected date time this way and need to reduce the offset.
$timeAinUTC = date["H:i A", strtotime["07am"]] - [offset];
i.e $timeAinUTC = date["H:i A", strtotime["07am"]] - [+9.30];
how can i get this kind of a work done with php's datetime ?
EDIT 1,
I tried this to add my offeset but it seems like i cannot provide double values like 2.30 hours or 2.50
It works when i ask it to add 2 hours this way.
strtotime[$current_time . "+2hours"];
but when i add like below , its wrong.
strtotime[$current_time . "+2.30hours"];
EDIT 2
All the sates available in AUS. ACT, NSW, NT, QLD, SA, TAS, VIC, WA
//wwp.greenwichmeantime.com/time-zone/australia/time-zones/
EDIT 3
I tried this as below as explained by a person in the answer.
$date = new DateTime['2013-10-01 01:45', new DateTimeZone['Australia/Melbourne']];
echo $date->format['Y-m-d h:i:s A'] . "
";
$date->setTimezone[new DateTimeZone['UTC']];
echo $date->format['Y-m-d h:i:s A'] . "
";
But it outputs,
2013-10-01 01:45:00 AM
2013-09-30 03:45:00 PM
How can this be wrong ? 2013-09-30 03:45:00 PM is wrong as per my understaing and actually it should be 10 hours behind from 2013-10-01 01:45:00 AM to be UTC, isnt it ?

Put this at the top of your php.
date_default_timezone_set["America/New_York"];
You can also do this.
$date = new DateTime[];
$date->setTimezone[new DateTimeZone['America/Detroit']];
$fdate = $date->format['Y-m-d H:i:s'];`
$fdate will print the appropriate time in new york with date.
