Radio Room Clock is most realistic when your PC is set to display time in 24-hour (military) format.
To set your PC to 24-hour format:
- Open Control Panel (switch to Classic Mode to show an itemized features list)
- Regional and Language Options
- Under Standards and Formats, click Customize
- Click the Time tab
- In the Time Format window, select HH:mm:ss
- Click OK
Traditionaly, the black hour-hand was set to GMT, and the lighter colored hour
hand was set to the local hour. As the ship sailed into different time zones,
only the lighter-colored hour hand would need to be adjusted.
At least once per day, the radio officer would check the accuracy of the
sweep-second hand against radio station WWV, or other stations transmitting
time signals throughout the
world, and adjust it to compensate as necessary.
Enjoy the rich, nostalgic tones of a grandfather clock right from your desktop or laptop PC speakers.
Each twenty-four hour day is divided into six four-hour watches: 12 to 4,
4 to 8, and 8 to 12 (for both AM and PM).
For example, one deck officer would typically
stand watch, or be on duty, from 12-noon until 4 PM, and then eight hours later,
he would come back on duty from 12-midnight until 4 AM.
The bell is rung in half-hour increments, beginning at half past midnight. Two strikes
denote an hour and a single strike denotes a half-hour.
For the mid watch (midnight to 0400, or "12 to 4") the bell would be struck as follows:
0030 1 bell
0100 2 bells
0130 2 bells, 1 bell
0200 2 bells, 2 bells
0230 2 bells, 2 bells, 1 bell
0300 2 bells, 2 bells, 2 bells
0330 2 bells, 2 bells, 2 bells, 1 bell
0400 2 bells, 2 bells, 2 bells, 2 bells
--End of Mid Watch, beginning of Morning Watch
and the sequence restarts . . .
0430 1 bell
0500 2 bells . . . and similar fashion for 0100, 0900, 1300, 1700, etc.
