The `toGMTString()` method converts a date to a string, using Internet GMT conventions. The exact format of the value returned by `toGMTString` varies according to the platform and browser, in general it should represent a human readable date string.

Note: `toGMTString` is deprecated and should no longer be used, it's only there for backwards compatibility, use `toUTCString()` instead.

## Syntax

    dateObj.toGMTString()

## Examples

### Example: Using `toGMTString`

In this example, the `toGMTString` method converts the date to GMT (UTC) using the operating system's time-zone offset and returns a string value that is similar to the following form. The exact format depends on the platform.

    var today = new Date();
    var str = today.toGMTString();  // deprecated! use toUTCString()

    console.log(str);               // Mon, 18 Dec 1995 17:28:35 GMT
