# SDL\_Time(3type)

SDL times are signed, 64-bit integers representing nanoseconds since the Unix epoch (Jan 1, 1970).

## NAME

SDL\_Time - SDL times are signed, 64-bit integers representing nanoseconds since the Unix epoch (Jan 1, 1970).

## HEADER FILE

Defined in SDL3/SDL\_stdinc.h

## SYNOPSIS

```
#include "SDL3/SDL.h"
```

**typedef Sint64 SDL\_Time;** **#define SDL\_MAX\_TIME SDL\_MAX\_SINT64** **#define SDL\_MIN\_TIME SDL\_MIN\_SINT64**

## DESCRIPTION

They can be converted between POSIX time\_t values with

**SDL\_NS\_TO\_SECONDS** () and

**SDL\_SECONDS\_TO\_NS** (), and between Windows FILETIME values with  **SDL\_TimeToWindows** () and

**SDL\_TimeFromWindows** ().

## AVAILABILITY

This macro is available since SDL 3.2.0.
