# PR_GMTParameters

Returns the time zone offset information that maps the specified

{ref}`PRExplodedTime` to GMT.

:::{note}

**Note:** Since this function requires GMT as input, its primary use

is as "filler" for cases in which you need a do-nothing callback.

:::

## Syntax

```{code}

#include <prtime.h>

PRTimeParameters PR_GMTParameters (

   const PRExplodedTime *gmt);

```

### Parameter

`gmt`

: A pointer to the clock/calendar time whose offsets are to be

  determined. This time should be specified in GMT.

### Returns

A time parameters structure that expresses the time zone offsets at the

specified time.

## Description

This is a frequently-used time parameter callback function. You don't

normally call it directly; instead, you pass it as a parameter to

`PR_ExplodeTime()` or `PR_NormalizeTime()`.

This is a trivial function; for any input, it returns a

{ref}`PRTimeParameters` structure with both fields set to zero.
