use TimeUnit. (Java 5 did not have all the units required, so TimeUnit2 was introduced because it had better conversion until Java 6 went out.)
A TimeUnit represents time durations at a given unit of granularity and provides utility methods to convert across units, and to perform timing and delay operations in these units. A TimeUnit does not maintain time information, but only helps organize and use time representations that may be maintained separately across various contexts. A nanosecond is defined as one thousandth of a microsecond, a microsecond as one thousandth of a millisecond, a millisecond as one thousandth of a second, a minute as sixty seconds, an hour as sixty minutes, and a day as twenty four hours.

A TimeUnit is mainly used to inform time-based methods how a given timing parameter should be interpreted. For example, the following code will timeout in 50 milliseconds if the lock is not available: 

  Lock lock = ...;
  if ( lock.tryLock(50L, TimeUnit.MILLISECONDS) ) ...
while this code will timeout in 50 seconds: 
  Lock lock = ...;
  if ( lock.tryLock(50L, TimeUnit.SECONDS) ) ...
Note however, that there is no guarantee that a particular timeout implementation will be able to notice the passage of time at the same granularity as the given TimeUnit.

    • convert

      public long convert(long sourceDuration, TimeUnit2 sourceUnit)
      Deprecated.
      Convert the given time duration in the given unit to this unit. Conversions from finer to coarser granularities truncate, so lose precision. For example converting 999 milliseconds to seconds results in 0. Conversions from coarser to finer granularities with arguments that would numerically overflow saturate to Long.MIN_VALUE if negative or Long.MAX_VALUE if positive.

      For example, to convert 10 minutes to milliseconds, use: TimeUnit.MILLISECONDS.convert(10L, TimeUnit.MINUTES)

      Parameters:
      sourceDuration - the time duration in the given sourceUnit
      sourceUnit - the unit of the sourceDuration argument
      Returns:
      the converted duration in this unit, or Long.MIN_VALUE if conversion would negatively overflow, or Long.MAX_VALUE if it would positively overflow.

    • convert

      public long convert(long sourceDuration, TimeUnit sourceUnit)
      Deprecated.
      Convert the given time duration in the given unit to this unit. Conversions from finer to coarser granularities truncate, so lose precision. For example converting 999 milliseconds to seconds results in 0. Conversions from coarser to finer granularities with arguments that would numerically overflow saturate to Long.MIN_VALUE if negative or Long.MAX_VALUE if positive.

      For example, to convert 10 minutes to milliseconds, use: TimeUnit.MILLISECONDS.convert(10L, TimeUnit.MINUTES)

      Parameters:
      sourceDuration - the time duration in the given sourceUnit
      sourceUnit - the unit of the sourceDuration argument
      Returns:
      the converted duration in this unit, or Long.MIN_VALUE if conversion would negatively overflow, or Long.MAX_VALUE if it would positively overflow.

    while (empty) {
      unit.timedWait(this, timeout);
      ...
    }

      obj - the object to wait on
      timeout - the maximum time to wait. If less than or equal to zero, do not wait at all.
      Throws:
      InterruptedException - if interrupted while waiting.
      See Also:

    • timedJoin

      public void timedJoin(Thread thread, long timeout) throws InterruptedException

      Performs a timed Thread.join using this time unit. This is a convenience method that converts time arguments into the form required by the Thread.join method.
      Parameters:
      thread - the thread to wait for
      timeout - the maximum time to wait. If less than or equal to zero, do not wait at all.
      Throws:
      InterruptedException - if interrupted while waiting.
      See Also:

    • sleep

      public void sleep(long timeout) throws InterruptedException
      Deprecated.
      Performs a Thread.sleep using this unit. This is a convenience method that converts time arguments into the form required by the Thread.sleep method.
      Parameters:
      timeout - the minimum time to sleep. If less than or equal to zero, do not sleep at all.
      Throws:
      InterruptedException - if interrupted while sleeping.
