Q: How to get the current date and time in PHP?



Ans: The time would go by your server time. An easy workaround for this is to manually set the timezone by using date_default_timezone_set before the date() or time() functions are called to.
I'm in Pune, India so I have something like this:
date_default_timezone_set('Asia/Kolkata');
Or another example of Nepal
date_default_timezone_set('Asia/Kathmandu');
You can also see what timezone the server is currently in via:
date_default_timezone_get();
So something like:
$timezone = date_default_timezone_get();
echo "The current server timezone is: " . $timezone;
So the short answer to your question would be:
// Change the line below to your timezone!
date_default_timezone_set('Asia/Kolkata');
$date = date('m/d/Y h:i:s a', time());

Then all the times would be to the timezone you just set :)

Q: How to check the current timezone in PHP?

Ans: Here is the code 

$timezone = date_default_timezone_get();
echo "The current server timezone is: " . $timezone;


NOTES:  Here is the Location that you can use to set your default dates and times.
