Methods

getPid :: EpochClock Replica Source #

getEvents :: Word60 -> EpochClock [Event] Source #

advance :: Word60 -> EpochClock () Source #

decode :: Word60 -> UTCTime Source #

Decode date and time from UUID epoch timestamp

encode :: POSIXTime -> Word60 Source #

epochTimeFromUnix :: Word64 -> Word60 Source #

Convert unix time in hundreds of milliseconds to RFC 4122 time.

getCurrentEpochTime :: IO Word60 Source #

Get current time in Time format (with 100 ns resolution). Monotonicity is not guaranteed.

runEpochClock :: Replica -> IORef Word60 -> EpochClock a -> IO a Source #

Run EpochClock action with explicit time variable.

runEpochClockFromCurrentTime :: Replica -> EpochClock a -> IO a Source #

Like runEpochClock, but initialize time variable with current wall time.
