This module provides the Ntp client related settings, types and re-exports used in a number of places throughout codebase.

Synopsis

Documentation

Arguments

:: IOManager	The global `IOManager` instance, set up by the application main function.
-> Tracer IO NtpTrace	Logging object
-> ( NtpClient -> IO a)	Action to run
-> IO a

Set up a NtpClient and pass it to the given action. The NtpClient is terminated when the callback returns.

Arguments

:: NtpClient
-> Bool	When `True` , will block and force a NTP check instead of using cached results
-> IO ApiNetworkClock
