Class DateFormatter


  • public class DateFormatter
    extends Object
    Formats dates and times into a given timezone in a variety of formats. The actual formats are provided by the FormatSettingsManager which is passed to the constructor. Also allows for formatting into arbitrary formats.

    This class is not thread-safe, primarily because DateFormat implementations are not synchronised. You should construct one instance of this class per thread or request.
