API Project: Timestamp Microservice - php5

User Stories:

1. I can pass a string as a parameter, and it will check to see whether that string contains
   either a unix timestamp or a natural language date (example: January 1, 2016)
2. If it does, it returns both the Unix timestamp and the natural language form of that date.
3. If it does not contain a date or Unix timestamp, it returns null for those properties.

Example Usage:

• http://emant.altervista.org/micro/api/timestamp/December%2015,%202015
• http://emant.altervista.org/micro/api/timestamp/1450137600

Example Output:

{ "unix": 1450137600, "natural": "December 15, 2015" }
