Enum AdjustRequest

pub enum AdjustRequest {
    ReportBootToUtcMapping {
        boot_reference: BootInstant,
        utc_reference: i64,
        responder: AdjustReportBootToUtcMappingResponder,
    },
}

Report UTC reference adjustment.

Allows components to request corrections to the reported UTC time. Very few components should be expected to have access to this capability.

Variants

ReportBootToUtcMapping

Requests that the callee changes its UTC time estimate.

Reports the caller’s desired correspondence between the boot timeline, and the UTC timeline.

The caller is required to provide both reference points so that any FIDL round-trip delays do not affect the callee’s interpretation of the caller’s intentions. For example, were the callee to use its own boot_reference value instead of a caller-provided one, long wall time delays between the caller’s and the callee’s sampling of boot_reference would introduce a skew. While this is unlikely to happen on a device to a meaningful extent, we established that this is the correct way to transmit such information.

To wit, we have observed delays in test environments. This is likely because test environments run on emulators in shared-resource settings, where unusually long delays are relatively common.
