Unix TimeStamp Converter Application Programming Interface (API)

We provide a simple API to allow easy conversion between the unix timestamp and the date string (formatted as "Y-m-d h:i:s").

To Convert From Date String to Unix TimeStamp

API example:
  https://helloacm.com/api/unix-timestamp-converter/?cached&s=2016-01-01%202:3:22
returns: 
  1451613802

To Convert From Unix TimeStamp to Date String

API example:

API Core Source Code in PHP

if (is_numeric($s)) {
  $data = date("Y-m-d h:i:s", (integer)$s);
} else {
  $data = strtotime($s);
}
