Nautical bell

Nautical bell is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

The task is to write a small program that emulates a [nautical bell] producing a ringing bell pattern at certain times throughout the day.

The bell times should be in accordance with [Greenwich Mean Time], unless locale dictates otherwise.

It is permissible for the program to daemonize, or to slave off a scheduler, and it is permissible to use alternative notification methods (such as producing a written notice "Two Bells Gone"), if these are more usual for the system type.
