Implementations§

Source §

impl UtcClock

Source

pub fn new(real_utc_clock: UtcClockHandle) -> Self

Creates a new UtcClock instance.

The real_utc_clock is a handle to an underlying Fuchsia UTC clock. It will be used once started.

Source

pub fn now(&self) -> UtcInstant

Returns the current Starnix UTC time.

In Starnix, UTC time is always running. It is started from backstop at Starnix boot, and adjusted to actual UTC once Fuchsia UTC clock is started.

Source

pub fn estimate_boot_time(&self, utc: UtcInstant) -> (BootInstant, bool)

Estimates the boot time corresponding to utc.

§Returns

zx::BootInstant: estimated boot time;
bool: true if the system UTC clock has been started.

Takes about 900ns worst case.
