The Binary Clock application has been updated to version 1.1 in BlackBerry AppWorld. This free app displays the time as a binary coded decimal, with the hours, minutes, and seconds of the day displayed in a colour of your choice.
New in Version 1.1
The update adds support for the recently announced BlackBerry 7 devices including the 9810, 9850, 9860, 9900, and 9930. Also the app now integrates with the native BlackBerry options menu, so you can change settings from there if you wish.
How to read
A binary coded decimal can be read with each column added up with each light worth (from top to bottom) 8, 4, 2, and 1, and the column on the left being worth 40, 20, and 10. For example the time in the above image would be 16 hours, 9 minutes, and 25 seconds.
