# zx_clock_get_monotonic

## Summary

Acquire the current monotonic time.

## Declaration

```c
#include <zircon/syscalls.h>

zx_time_t zx_clock_get_monotonic(void);
```

## Description

`zx_clock_get_monotonic()` returns the current time in the system
monotonic clock. This is the number of nanoseconds since the system was
powered on. It does not always reset on reboot and does not adjust during
sleep, and thus should not be used as a reliable source of uptime.

## Rights

TODO(fxbug.dev/32253)

## Return value

`zx_clock_get_monotonic()` returns the current monotonic time.

## Errors

`zx_clock_get_monotonic()` cannot fail.
