Functions

func NewNTPGoogleConfig

func NewNTPGoogleConfig() config.NTPConfig

NewNTPGoogleConfig creates an NTPConfig object that configures NTP to use time.google.com. This is a useful default for tests, for example, to avoid loading a configuration file just to have an NTPConfig.

func NewSyncTime

func NewSyncTime(ntpConfig config.NTPConfig, syncPeriod time.Duration, customQueryFunc func(options NTPOptions) (*ntp.Response, error)) *syncTime

NewSyncTime creates a syncTime object. The customQueryFunc argument allows the caller to set a different NTP-querying callback, if desired. If set to nil, then the default queryNTP is used.

Types

type NTPOptions

type NTPOptions struct {
	Hosts        []string
	Version      int
	LocalAddress string
	Timeout      time.Duration
	Port         int
	HostIndex    int
}

NTPOptions defines configuration options for an NTP query

func NewNTPOptions

func NewNTPOptions(ntpConfig config.NTPConfig, hostIndex int) NTPOptions

NewNTPOptions creates a new NTPOptions object.

type SyncTimer

type SyncTimer interface {
	StartSync()
	ClockOffset() time.Duration
	FormattedCurrentTime() string
	CurrentTime() time.Time
	IsInterfaceNil() bool
}

SyncTimer defines an interface for time synchronization
