    • getCurrent

      public static final TimeZone getCurrent()
      Returns the current time zone; never null. This is the time zone that every other objects shall use, unless they have special consideration.

      Default: If setThreadLocal(java.util.TimeZone) was called with non-null, the value is returned. Otherwise, TimeZone.getDefault() is returned,

    • setThreadLocal

      public static final TimeZone setThreadLocal(TimeZone timezone)
      Sets the time-zone for the current thread only.

      When Invoking this method under a thread that serves requests, remember to clean up the setting upon completing each request. 

      TimeZone old = TimeZones.setThreadLocal(newValue);
try { 
  ...
} finally {
  TimeZones.setThreadLocal(old);
}
      Parameters:
      timezone - the thread time zone; null to denote no thread time zone (and the system's timezone will be used instead)
      Returns:
      the previous thread time zone, or null if no previous time zone
