Enum UtcTime 

pub enum UtcTime {
    Reliable(u64),
    LastKnown(u64),
}

An enum describing the current UTC timestamp the real-time clock is aware of.

The timestamp is expressed as Matter-epoch microseconds.

Variants

Reliable(u64)

The RTC is actively tracking the current time, anchored at the given Matter-epoch microseconds value.

LastKnown(u64)

The RTC is not currently tracking the current time, but the given Matter-epoch microseconds value is the last known good UTC time persisted on the device.

Do note that a “last known” time is always available, as the firmware build timestamp is used as the initial value on a freshly-flashed device.

Implementations

impl UtcTime

pub const fn reliable(&self) -> Option<u64>

Return the current UTC time if available, or None if no reliable time is currently tracked.

pub const fn any(&self) -> u64

Return the current UTC time if available, or the persisted LKG UTC otherwise.

pub const fn reliable_secs(&self) -> Option<u64>

Return the current UTC time in seconds if available, or None if no reliable time is currently tracked.

pub const fn any_secs(&self) -> u64

Return the current UTC time in seconds if available, or the persisted LKG UTC otherwise.
