Ships Bell, Sailor's Clock

The bell will sound time signals.
The time between signals is the time it takes for the sand to run out in a time glass.
In the real world the sand runs through in 30 minutes.
In a SIM it takes 5 minutes.

You can control the bell by a menu that opens when you touch the bell.
The actual time is shown in the menu.
In the menu the owner can:

1. Sound the bell, which will repeat the last signal
2. You can switch between real time and SIM time
3. The bell can be set to any timezone around the world.

When other people touch it, they can only sound the bell.

About the "double strike system"

The bell uses the double strike system marking off the series of watches that make up the sailor's day
In Real Time a watch is 4 hours in a SIM it is 40 minutes since a SIM has 6 days and 6 nights within 24 hours.
One glass in Real time is 30 minutes long, in a SIM it will be 5 minutes ( the time it takes for the sand to run out in a time glass )
in both cases we get 6 watches by 8 glasses each, which equals 48 glasses around the clock

The first watch begins at 8 o'clock in the evening.

Each Watch begins with 4 double strokes (8 strokes)
After half an hour the bell strikes one
After 1 hour the bell strikes one double stroke
After 1.5 hours the bell strikes one double and a single
After 2 hours the bell strikes two double strokes
After 2.5 hours the bell strikes two doubles and a single
After 3 hours the bell strikes three double strokes
After 3.5 hours the bell strikes three doubles and a single
After 4 hours the watch is completed and a new one starts with 4 double strokes
