# GetZeroTimestampPeriod

Gets the zero time stamp of the clock device.

## Declaration

```occ
uint32_t GetZeroTimestampPeriod();
```

## Return Value

Return Value The zero time stamp of the clock device.

## Discussion

Discussion The return value indicates the number of sample frames the host can expect between successive timestamps returned from GetCurrentZeroTimestamp. In other words, if GetCurrentZeroTimestamp returns a sample time of x, the host can expect that the next valid timestamp it recieves will be x + GetZeroTimestampPeriod. This method synchronizes by using the work queue created by the object.
