    • getSafeTimeMillis

      public static long getSafeTimeMillis()
      Returns a "safe" current time in milliseconds.
      Returns:

    • computeSafeWaitTime

      public static long computeSafeWaitTime(long ldtTimeout)
      compute the number of milliseconds until the specified time.

      Note: this method will only return zero if ldtTimeout == Long.MAX_VALUE.

      Parameters:
      ldtTimeout - the timeout as computed by getSafeTimeMillis()
      Returns:
      the number of milliseconds to wait, or negative if the timeout has expired

    • getTimeZone

      public static TimeZone getTimeZone(String sId)
      Gets the TimeZone for the given ID.

      This method will cache returned TimeZones to avoid the contention caused by the TimeZone.getTimeZone(String) implementation.

      Parameters:
      sId - the ID for a TimeZone
      Returns:
      the specified TimeZone, or the GMT zone if the given ID cannot be understood.
