# CVTimeStamp

A structure for defining a display timestamp.

## Declaration

```swift
struct CVTimeStamp
```

## Overview

Overview This structure is designed to be very similar to the audio timestamp defined in the Core Audio framework except that, in CVTimeStamp, floating-point values are not used to represent the video equivalent of sample times.

## Topics

### Initializers

- [init()](corevideo/cvtimestamp/init().md)
- [init(version:videoTimeScale:videoTime:hostTime:rateScalar:videoRefreshPeriod:smpteTime:flags:reserved:)](corevideo/cvtimestamp/init(version:videotimescale:videotime:hosttime:ratescalar:videorefreshperiod:smptetime:flags:reserved:).md)
- [init(videoTime:hostTime:rateScaler:videoRefreshPeriod:smpteTime:topField:bottomField:)](corevideo/cvtimestamp/init(videotime:hosttime:ratescaler:videorefreshperiod:smptetime:topfield:bottomfield:).md)
