Method Detail

isSecs

public static boolean isSecs(long time)

Tests whether the supplied value appears to be a second based timestamp.

Parameters:

time - candidate timestamp, expected to be no earlier than EPOCH_SECS

Returns:

true if time falls between EPOCH_SECS and MAX_SECS

isMillis

public static boolean isMillis(long time)

Tests whether the supplied value appears to be a millisecond based timestamp.

Parameters:

time - candidate timestamp, expected to be within the millisecond range

Returns:

true if time lies between EPOCH_MILLIS and MAX_MILLIS

isMicros

public static boolean isMicros(long time)

Tests whether the supplied value appears to be a microsecond based timestamp.

Parameters:

time - candidate timestamp, expected to be within the microsecond range

Returns:

true if time lies between EPOCH_MICROS and MAX_MICROS

isNanos

public static boolean isNanos(long time)

Tests whether the supplied value appears to be a nanosecond based timestamp.

Parameters:

time - candidate timestamp, expected to be at least EPOCH_NANOS

Returns:

true if time is not less than EPOCH_NANOS

toSecs

public static long toSecs(long time)

Converts the supplied time to seconds.

Parameters:

time - timestamp in seconds, milliseconds, microseconds or nanoseconds

Returns:

the equivalent value in seconds

toMillis

public static long toMillis(long time)

Converts the supplied time to milliseconds.

Parameters:

time - timestamp in seconds, milliseconds, microseconds or nanoseconds

Returns:

the equivalent value in milliseconds

toMicros

public static long toMicros(long time)

Converts the supplied time to microseconds.

Parameters:

time - timestamp in seconds, milliseconds, microseconds or nanoseconds

Returns:

the equivalent value in microseconds

toNanos

public static long toNanos(long time)

Converts the supplied time to nanoseconds.

Parameters:

time - timestamp in seconds, milliseconds, microseconds or nanoseconds

Returns:

the equivalent value in nanoseconds
