How to add Date Time Month by timezone in Zoho CRM

I try to add the Date and time in Zoho CRM but it not added because the format of date-time is not correct. So used the below code and try to push with API PUSH.  It also works when you push the perfect date in MySQL and show date time in a nice format in HTML Output.

Used below code for entry perfect date time with timezone in CRM, MySQL or HTML.

Can change timezone PHP variable as you required, timezone table are below mention after code.

$timezone = 'GMT';
$datetime = new DateTime($start, new DateTimeZone($timezone));
$date1 = $datetime->format('Y/m/d h:i a');
$timestamp= strtotime($date1);
$start_date = date('c', $timestamp);

 

The output of the above code :

Dec 23, 2020 07:35 PM
