Multitimezone website

This is first time I get project where I should consider multiple timezones. Although time precision is not critical in this project I want to build in a right way.

So far in my projects I handle time in following way:

1. in index.php I set 
PHP Code:
as in Turkey time same every where within Turkey.
2. In in database I set time column as DATATIME type
3. and I set the value of the time columns with value from 
PHP Code:
$date['created_at'] = date((time(), 'Y-m-d hh:mm:ss'); 

And now I working on a project (Which give consultation service, also consultants will give appoitment for users for online conversation) that will have users from different countries. 
How should I handle  time here?

Thanks in advance...

It is not what I am asking. I am asking:
1. Should I continue use DATETIME as type of time field in db. or I should use TIMESTAMP. or even integer and use unix time.
2. I am want to know how you guys handled time in this situation?

DATETIME type  - has a range is '1000-01-01 00:00:00' to '9999-12-31 23:59:59'.

TIMESTAMP type - has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC.

Read the below article, they use a DATETIME field.

Because of potential differences in timezone settings between server and database, I find it's best to set the timezone in the application to UTC for these types of websites. That's what most databases default to, I believe. Then store a timezone / offset for each user, and a system wide default timezone (in case the user's haven't specified a timezone). Then you can use PHP's DateTime and DateTimeZone to display the correct time, adjusted for the user's timezone. Something like:

$date = new DateTime($originalDate, new DateTimeZone($userTimezone));
echo $date->format('...');
