PROTOCOLS
DeprecatedNetworkSync
Defined in fuchsia.time/deprecated_network_sync.fidl
Emits UtcUpdated events when the serving program changes the UTC offset tracked by
ZX_CLOCK_UTC.
Do not take this API as a dependency, it will be deleted in the near future.
UtcUpdated
Notifies the client that UTC has changed, along with the monotonic clock's value when the change was made.

Utc
Defined in fuchsia.time/utc.fidl
Metadata about a device's approximation of UTC time, commonly referred to as "system time."
WatchState
Notifies clients of updates to the UTC timeline. The first call on a channel returns immediately, and subsequent calls on the same channel will return when the state has changed.

The clock has been initialized to a known-prior reference time but may be highly inaccurate. |
EXTERNAL |
3 |
The clock has been initialized from a suitably accurate external time source. For many devices the most common external time source is a network time server. |
