What is time period?

Famous quotes containing the words time and/or period:

    Still it wouldn’t reward the watcher to stay awake
    In hopes of seeing the calm of heaven break
    On his particular time and personal sight.
    That calm seems certainly safe to last tonight.
    Robert Frost (1874–1963)

    The post-office had a great charm at one period of our lives. When you have lived to my age, you will begin to think letters are never worth going through the rain for.
