+### the second extension
+
+Fugit accepts cron strings with five elements, `minute hour day-of-month month day-of-week`, the standard cron format or six elements `second minute hour day-of-month month day-of-week`.
+
+```ruby
+c = Fugit.parse('* * * * *') # every minute
+c = Fugit.parse('5 * * * *') # every hour at minute 5
+c = Fugit.parse('* * * * * *') # every second
+c = Fugit.parse('5 * * * * *') # every minute at second 5
+```
