Want to get times accroding to my time zone not the servers time zone

Want to get times accroding to my time zone not the servers time zone

I'm from India. Hosting my site in 000webhost. I'm tracking the IPs
visiting and their times. but the time is wrong i.e I think times are
according to the time zone of 000webhost server. How to convert them
according to Indian timezone.
this is the code I am using:
date_default_timezone_set('Asia/Kolkata');
$query="INSERT INTO visitor_ip ";
$query.="VALUES('{$_SERVER["REMOTE_ADDR"]}',now())";
