=============


1. Time and Date
----------------
The file date.pl demonstrates some ways to manipulate date objects.
Run this example.


2. Writing dates to a file 
--------------------------
The time() function returns a timestamp representing the number 
of seconds elapsed since Jan 1, 1970 (GMT).
Write a program that creates a file containing 100 random timestamps between
now and Jan 1, 1970 GMT.


3. Difference between dates
---------------------------
Write a perl program that reads the previously created file and finds
the date that is the closest to 9/9/1999.


4. Writing to files
-------------------
Use superbowl.html from before. Extract the date from the table cells and
print them to a file. Separate each item by some delimiter, such as "|"
