Constructor Details

UTCTime

public UTCTime(Instant value)

Method Details

now

public static UTCTime now()

Obtains the PTP (Precision Time Protocol) synchronized current UTC time. In case of a Linux machine, this will make a native call clock_gettime inorder to get time from the system clock with nanosecond precision. In case of all the other operating systems, nanosecond precision is not supported, hence no native call is made.

Returns:

current time in UTC scale

after

public static UTCTime after(scala.concurrent.duration.FiniteDuration duration)

value

public Instant value()

Specified by:

value in interface TMTTime

toTAI

public TAITime toTAI()

Converts the UTCTime to TAITime by adding the UTC-TAI offset. UTC-TAI offset is fetched by doing a native call to ntp_gettimex. It ensures to get the latest offset as updated by the PTP Grandmaster.

Returns:

TAI time at the given UTC time
