Methods

GetMillisFromNanos(long)

Returns time measured in milliseconds since Unix epoch from the time in nanoseconds. Idea is that nano part of time shall be within [0..999999] interval so that the following equation always holds:

GetMillisFromNanos(timeNanos) * 1_000_000 + GetNanoPartFromNanos(timeNanos) == timeNanos
GetNanoPartFromNanos(long) 
public static long GetMillisFromNanos(long timeNanos)

Parameters

timeNanos long

The time measured in nanoseconds since Unix epoch.

Returns

long

The time measured in milliseconds since Unix epoch.

GetNanoPartFromNanos(long)

Returns nano part of time. Idea is that nano part of time shall be within [0..999999] interval so that the following equation always holds:

GetMillisFromNanos(timeNanos) * 1_000_000 + GetNanoPartFromNanos(timeNanos) == timeNanos
GetMillisFromNanos(long) 
public static int GetNanoPartFromNanos(long timeNanos)

Parameters

timeNanos long

The time measured in nanoseconds since Unix epoch.

Returns

int

The time measured in milliseconds since Unix epoch.

GetNanosFromMillisAndNanoPart(long, int)

Returns time measured in nanoseconds since Unix epoch from the time in milliseconds and its nano part. The result of this method is timeMillis * 1_000_000 + timeNanoPart.

public static long GetNanosFromMillisAndNanoPart(long timeMillis, int timeNanoPart)

Parameters

timeMillis long

The time in milliseconds since Unix epoch.

timeNanoPart int

The nanoseconds part that shall lie within [0..999999] interval.

Returns

long

The time measured in nanoseconds since Unix epoch.
