# PR_TicksPerSecond

Returns the number of ticks per second currently used to determine the
value of {ref}`PRIntervalTime`.

## Syntax

```{code}
#include <prinrval.h>

PRUint32 PR_TicksPerSecond(void);
```

### Returns

An integer between 1000 and 100000 indicating the number of ticks per
second counted by {ref}`PRIntervalTime` on the current platform. This value
is platform-dependent and does not change after NSPR is initialized.

## Description

The value returned by `PR_TicksPerSecond()` lies between
`PR_INTERVAL_MIN` and `PR_INTERVAL_MAX`.

The relationship between a {ref}`PRIntervalTime` tick and standard clock
units is platform-dependent. PR\_`PR_TicksPerSecond()` allows you to
discover exactly what that relationship is. Seconds per tick (the
inverse of PR\_`PR_TicksPerSecond()`) is always between 10
microseconds and 1 millisecond.
