Method Summary

Modifier and Type	Method	Description
`EntryIndexProxy<ZonedDateTime>`	`getTime()`	Returns consolidated time output by the service in UTC.
`ProofMapIndexProxy<PublicKey,ZonedDateTime>`	`getValidatorsTimes()`	Returns the table that stores time for every validator.
`static TimeSchema`	`newInstance(View dbView, String name)`	Constructs a schema of the time oracle instance with the given name.

Method Details
- newInstance
  
  static TimeSchema newInstance(View dbView, String name)
  
  Constructs a schema of the time oracle instance with the given name.
  
  Parameters:
  
  dbView - the database view
  
  name - the name of the time oracle service instance to use
  
  Throws:
  
  IllegalArgumentException - if there is no service with the given name or it is not an Exonum time oracle
- getTime
  
  EntryIndexProxy<ZonedDateTime> getTime()
  
  Returns consolidated time output by the service in UTC.
  When this time oracle instance is started, the consolidated time remains unknown until the transactions with time updates from at least two thirds of validator nodes are processed. After that the time will be always present.
- getValidatorsTimes
  
  ProofMapIndexProxy<PublicKey,ZonedDateTime> getValidatorsTimes()
  
  Returns the table that stores time for every validator. Note that this is a proof map that uses non-hashed keys.
